Top budget boosters. What kind of sound enhancer is best? Tubes and transistors

A current music lover will pay a fortune for a good supporter, which, of course, is the case. It would seem that you have active computer speakers - connect the device and enjoy. Prote catharsis does not come out... - the sound comes out in the middle... And for those who don’t even feel how the hi-fi equipment is playing, it’s difficult to explain in detail. Fortunately, lovers of good music are now increasingly stuck, and they are not asking for royal bloodshed for the heavy electronics.

What is so wonderful about boosting the sound of speakers, which is the heart of the audio system? Among a million different evidences, the obvious one comes to mind. It increases the strength of the signal. It is no secret that any information in modern technology is transmitted most importantly using electric power. Both digital and analogue devices can be configured for the robot to transfer information to the unit from the vessel or from another device. So let's be friends.

At the output of the program, the electrical circuits are always even weaker, and I want to replace all the necessary information for the creation of a serious work. Not for any speaker who respects himself, such a whisper is unpleasant. The skin column, skin speakers check for adequate food and, connected to the transmitting music of the BRAIN, “starve”. In such minds, the stench sounds inconceivable and inconceivable.

The axis is here to help and our hero comes - adding force to the sound. A good booster prepares the sound for acoustics and electrical connections, infecting the speakers with its energy through the linear outputs. As it seems, a completely different song is beginning.

Without a doubt, in the twenty-first century, people began to make their contribution from an increase in machine development: the workers at once became very different from each other. Tim is no less, you can do a manual classification, which will help you navigate them better.

See people

Well, there are three types of such equipment that make audio louder and louder:

Front. If a device, for example, such as a microphone is located to the right of a bad sound source, the speaker collects and adds information about it, adding to the complexity.

Kintseviy. Please, don’t bother with your direct obligations anymore - I’ll make the sound louder. You can learn from recording studios among other professional skills.

Integral. Mix of the two front ones. The most extensive system available in stores. However, any combination of solutions results in a much reduced sound brilliance, even with specialized boosters. It also benefits from price and versatility.

Divide the equipment and the method of signal transmission:

Analog booster. It works with electric pumps, which have better energy characteristics. To connect to digital technology, you need to change the connection.

Digital booster. It converts the digital signal into an analog signal at the output, “reasonably” for the speakers and adds tension to them.

Classes of podsilyuvachyv

Transistors, the elements that add strength to the signal in the middle of the booster, work differently. Their type of floor, however, is more varied, which makes it easier to focus on the main importance. In short, without neglecting the delicate functioning of the radio component and not explaining its devices, we will increase respect for the performance characteristics of the relevant classes.

Subclasses A, B, AB, N and others similar. Although we would like to change the stage of opening the transistors to pass the stream into the Lancug, the principle is the same. The main problem with all devices of this type is that the initial moment of transmission of the stream has non-linear response to the input signal. Everything in the design of this type of technology is aimed at combating them. What to do before changing the CCD and causing serious heating. There is a serious increase in size with increased tension - for a large device, and the smoothness of the sound is small - because the device is small. Class A is considered to be the most accurate and the least efficient, and as a result, the least productive.

Subject to class D. Transistors in which act as switches, open mitt and immediately pass current. This will lead to increased prevalence of non-linear processes. Briefly speaking, this type of support extends all the way to the anterior family. Playing in the CCD, the stench is evident when the sound range is opened, which is especially noticeable in the high frequency region. For those who are looking for a compact booster in a car, this class may be especially useful.

These devices are also seen as for the confessions, and for the Viconn.

On integrated circuits. As they say, it’s cheap and mighty angry. It plays frequently, bravuraly and loudly. It spoils the entirety of the painting, and does not reveal the depths and softness. By the way, you love parades and marches. The compact elemental base can easily fit into a small body. It is often discussed how to balance a car's solution. Among such devices there are often so-called receivers, which include a number of related functions. For example, they may have integrated Wi-Fi and Bluetooth modules. In a word, it is developing rapidly. There are also expensive models with amazing sounds that reach the hi-end class.

on transistors. The technology has been developed and verified. The sound lies in the core of the transistors. Today's radio components allow you to reach, with a minimum of interaction, a wealth of nuances with an easy, playful and dynamic composition. There are several copies that sound very gentle, homely. All smells are universal. They can work with any acoustics. Although, not everything is clear here. Class A shows the widest range, but also falls in terms of QCD and strength, which is more useful in the selection of acoustics. Class systems or D are less vibable. We are tough on people with low sensitivity. In this case, there is no sense of tightness or closedness in the dynamic range.

Lampov. They are often robbed of prices. The creation is warmer and more natural. Ideally convey the timbre of the voice and truly reveal the entire sound palette of the instrument that is playing. It is best to show yourself in tandem with soft speakers based on paper or similar material with mechanical power.

Hybrid The remaining hours are especially popular. Here the lamps output the input signal, and the pumping of the speakers is carried out by cascades that enhance the transistor circuits. The combination of “sword and ploughshare” gives warmth, without the harm of QCD and allows precise acoustics. I have the power to “roll out” tight speakers with good lows.

It is necessary to note that in this nomenclature there is a tautology that has been consolidated historically. In the midst of overinsurance of more discharges of boosters, the main and main unit is still lost, the transistor. It’s just that we see different things. In devices based on integrated circuits, the transistors are tightly packed in a granular piece of silicon, in lamps around the triode in a glass flask. Apart from that, they don’t care about those that all these devices are collected from the same real, or differently shaped elements, they call them transistors, in which they represent a near-conductor part. Before speaking, at the same time, Milkov’s formulation “enhancing sound on a transistor” is emphasized, which is also incorrect because there are currently a lot of boosting transistors, at least one per cascade.

Select a booster that improves the characteristics of the speakers

Choosing a good audio booster for your home that matches your current needs and stress is not trivial. Bring wholesome peace to the engineering department. It is necessary to improve the characteristics of the speakers and speakers in order to improve their performance at the same time. And also increase the size and acoustics of the location, de roztashovuvatime and the gratification of musical possession. Before that, you will have to pay for the costs by setting the level of capacity available to you.

Why do you need to kill your respect? You can see a number of important points:

We must first evaluate the level of intermodulation and transient reactions. These values ​​are rarely indicated by the distributors, but their presence in the passport confirms a serious approach to the authorities. In the smallest colors of the first, the value does not exceed one hundredth. The home extension has a sufficient display of no more than three.

Signal/noise indicator. Then, if you turn the boost volume control all the way down, you equalize the value of the distortion with the amplitude of the core signal that is visible. The higher the number, the purer the sound will be.

Frequency range. The wider it is, the better it is. It is especially good that this range goes to an area that is not perceptible to the human ear - this guarantees the robot without any interference. I understand, for other equals.

It is important to understand the sensitivity and support of the columns that must be supported. Acoustics with low sensitivity will require a more powerful device. The smallest speaker support, the least flexible for booster, can produce short circuits and outputs in harmony with the entire audio system. Moreover, although it is not safe, with great difference it is important to change the volume of the music before it warms up.

The booster system is double-branched for the ability to create stereo. And connect the subwoofer to the main channel. If you want a better choice for a bass player, a discrete monopod is better.

Possible options

To make it easier to understand the variety of sound reinforcement technology, you can take a look at specific models that have proven themselves well on the market among music lovers. Insanely, the skin can be used to increase the intensity of the sound, in addition to bringing its power to the same model of the birthplace of Vikonian music. You need to remember. Always follow the main rule when purchasing any audio device: listen, listen, and listen again. The most powerful way to perceive the sound is that which is the first thing you need to focus on.

• Good tension
• Creates a wide and voluminous sound space
• Є phonorector and MM-reading head, for vinyl lovers
• Є auto-wake function

• Type of balance regulator
• Plastic different line outputs
• The level of noise is significantly lower than in other similar systems

Integral booster for the legendary multimedia brand. It is the cheapest from the line, but also has the same unique technologies as the older models. One hundred per channel is quite strong, and such force is entirely sufficient for any kind of speakers. He shows himself kindness when creating complex musical compositions. The range of typical music ranges from symphonic – to contrasting – rap. The booster saves the original sound without being too light and coloring less of the bark.

The sound is direct and inviting, the design is reliable, the appearance is strict and laconic. I bought a valid copy for my own money.

• Bluetooth presence. Possibility to broadcast music via radio channel from your phone or to speakers.
• Creation via USB and MicroSD cards
• Gwent roses for acoustics
• Small size
• Low price

• Outer living block
• The strain is not too great

A nice little class D booster with dartless tracking via Bluetooth. It works especially well at high frequencies, but also at low frequencies throughout the year. Pure and very clear sound. At the skin outputs there are two channels of 30 watts each with a 4 ohm speaker support. The aluminum body has a pleasant texture, fine and miniature. Good for not too hard acoustics. Sufficient for an average sized room.

• The actual tightness is lower than stated (maximum 10 watts per channel, although the distributor says 50, don’t wash yourself, so it’s peaky)
• The price is well deserved

Regardless of the low power factor, it copes with serious columns. Wanting to do good, it only plays at half its intensity (about 4 waves per channel). For such minds and with decent equipment, the sound is good, beyond the minimal, and the breadth of frequencies that are created is more or less satisfactory.

Visnovok

Their butts looked like class D devices, which were modern and suitable for home use. The stench is of low intensity and gives a rich sound picture. And it is recommended for amateurs and primary musicians who want to expand their musical knowledge.

Low-frequency boosters are an invisible part of a home sound system. The stench will become stagnant as a pressure booster for low-pressure devices by creating and reaching the parameters of the signal to pump up the acoustic system. There are also devices created with the use of stress-enhancing forces, but most often their technical parameters and functional capabilities deprive them of the best results. Many lovers of high-quality sound often hesitate to buy an external amplifier that best suits their needs. This article will try to help you understand what kind of booster to choose for your home.

Types of supporters

The functions that come together are divided into three groups:

1. Front boosters. They are used to prepare a low-pressure input signal until it becomes stronger. Ensure that they are placed near the signal socket to prevent interference from other electrical and electronic devices. As a rule, problems arise from the input switching block, the volume control block and the timbre of the same booster, which increases the signal amplification to the level of 1-2 V. The front boosters cause stagnation of the strength booster;
2. Kintsev's boosters(Powerful exertion). Their significance lies in the amplification of the signal to the level and strength necessary for normal operation of the acoustics. Yes, it’s possible to adjust any parameters of the signal;
3. More strength. At the same time, the functions of the front and rear boosters are reduced, giving them more operational capabilities. Moreover, this skill often appears to be less than the total skill of the front and back forces taken.

Based on the type of elemental base where the boosters will be added, they are divided into:

• Power lamps. Their advantages are:

• high-pitched sound behind a remarkably simple scheme;
• less harsh and “warm” sound;
• less noise;
• softer signal exchange when re-vantaged;
• Resistance up to short bursts at the vantage point.

There are many lovers of high-quality sound that give preference to the tube boosters themselves;

• Transistor boosters:

• The stench is based on frozen field-effect and bipolar transistors as booster elements. To achieve approximately the same parameters with tube boosters, transistors use folding circuitry. Also, when replacing lamp boosters, they are particularly advantageous in protecting the output cascades and life blocks from overvoltage and short circuits. Today, instead of transistor boosters on discrete elements, devices based on integrated circuits are often used;
• Supports on integrated circuits. Use integrated circuit chips to replace all the main stages of the permanent booster. The advantages of such boosters include their compactness, minimal strength of external elements and high maintainability;
• Hybrid boosters. They are constantly developing both electronic tubes, conductor devices and integrated circuits with all their advantages and disadvantages.

Main parameters of boosters

The sound quality of the booster in most cases is determined by the parameters of the end booster, both continuous and continuous booster, which enters the warehouse. Therefore, in the future, when choosing a booster for the booth, you will need to consider the very best boosters.

What parameters should be used to increase respect in the first place when choosing a home booster? The following parameters are included:

• Number of power channels;
• The tension that develops in a woman;
• Contribution coefficient;
• Operating frequency range;
• speed of rise of the output signal;
• Improved signal/noise.

Number of power channels

The number of channels is selected depending on the configuration of the speaker system, following the principle “each speaker is required to work only with its own channel, and one channel is not required to work with more than one speaker.” This principle is to ensure that the sound is as clear as possible. It’s important to say something about the choice of boosters for playing music and AV receivers in your home theater. The first priority is two channels for creating stereo formats, which have the most music recorded. The home cinema can be equipped with acoustic configurations from the available 5.1 to 9.2. This is the criterion for selecting the number of channels in the AV receiver.

The tension that develops in a woman

Professionals in the field of sound engineering give such pleasure: because there is a need to add reinforcement and acoustic system, then first select and buy acoustics, and then enhance it. First of all, it is much simpler to choose the booster from the acoustics, but in another way, the added acoustics provide some guidelines for choosing the booster you want from the point of view of your tension. These guidelines are:

• Most exercisers give the muscle strength during an hour of work at approximately 70% of its strength. For acoustics, set this parameter to approximately 90%. Therefore, the most optimal ratio is the tension of the acoustics to the tension of the booster, which is approximately 1:1.6. In other words, the booster is responsible for providing 60% more pressure on the acoustics;
• With plenty of virobniks, the power to demonstrate the maximum effort of the booster. It is necessary to focus on its nominal pressure, since it itself means that it allows the sound to be produced at a given level;
• The intensity of the booster is related to the sensitivity of acoustics. The rest is measured at decibels. There is a simple truth here: a decrease in the sensitivity of the system acoustics by 3 dB results in the reduction of the increased strength of the booster.

Contribution coefficient

It consists of two indicators – the coefficient of intermodulation reactions and the coefficient of harmonic reactions. The grievances are asked in the hundreds and indicate the zeal for the sound at the output of the booster. As a rule, the Hi-Fi class complies with the DIN 45500 standard, which means the following values ​​of these parameters:

• The coefficient of intermodulation effects is slightly more than 3% for smooth frequencies 250 – 8000 Hz;
• The coefficient of harmonic effects is less than 1% for smoothies of frequencies 40 – 12500 Hz.

Just focus on these meanings.

Operating frequency range

Most people's hearing senses sounds at frequencies ranging from 20 Hz to 20 kHz. The ideal booster is responsible for its direct amplitude-frequency response (AFC). Real booster sounds rarely have a direct frequency response, but this may cause unevenness in the operating frequency range, especially in the high-frequency region. Therefore, it is important to choose a booster with the widest possible frequency range; the optimal upper limit may exceed 20 kHz at most times.

Slew speed of the output signal

This parameter means the strength of the signal without interference, more precisely, from the specified values ​​​​of the coefficient of interference, creating sharp bursts of the sound signal - the so-called front signal, which often breaks, for example, when hitting the container lkah. Professional audio engineers often use the term “voice hour” to change the frequency input signal. This parameter is inextricably linked with the upper cordon of the operating frequencies - whichever is greater, then the value of this parameter is greater. For a high-acid power supply, this parameter is required to be less than 5V/µs.

Minimum permissible vantagement

The support of the vantage, then, of the acoustic system, lies and strength, which develops under strength, and its reliability and safety. Obviously, a column that operates at 4 ohms will push the boost channel much stronger, below 8 ohms. Reinforcement – ​​for acoustics with low support, a tighter booster is necessary. But don’t forget that if you connect 4-ohm acoustics to a booster that is insured for work with 8-ohm inputs, you can over-engineer and end up okay. Therefore, the minimum acceptable value is the importance of respect for brothers and sisters. On the other hand, since there is an increase in insurance coverage for work with 4-dimensional reserves, then in jobs with great support, you may not develop a great deal of effort, which, with a large reserve, is not so important.

Improved signal/noise

This parameter indicates the relationship between the intensity of the core and noise signals. It is measured in decibels to the maximum position of the volume control when the input signal is turned off. The higher the value of the parameter, the greater the brightness of the produced sound. It is important to choose a booster that has a value of at least 90-100 dB.
- The choice of model of a booster will not always come down to the value and prestige of the picker. However, it’s also unreasonable to buy such a cheap model - you won’t be surprised by the miracle, even though the stink will disappear.
- Buy the product from stores that have the opportunity to verify it in real minds, you can only decide in advance on the choice of its model.
- It is necessary to select a strength device with a reserve according to the strength, so as not to use it at pressures close to the maximum, as this will sharply reduce the reliability of the device. For example, a power supply with a maximum power of 100 W ensures that the work can be performed with less power, approximately twice the minimum.
- It is also necessary to focus on the area of ​​space in which sound-creating technology is used. Set the target tension of the skin channel to 3 – 5 W per square meter. The area does not exceed 15 sq. m., then it is necessary to use the first number, and for areas over 20 sq.m. - Another.
- It is important to choose a connection for any connection of acoustics that is carried out not using spring clamps, but using terminals with threaded clamps. This, first of all, ensures more reliable fastening of cables, and, in other words, ensures the structural integrity of the device and its suitability to the Hi-Fi class.
- It’s completely unnecessary to buy the remaining model. It turns out that a booster that has been lying in police custody or a warehouse for a long time becomes completely cheaper without incurring any cost.

At this time, the idea has become even broader that Hi-Fi technology, released in the 70s, 80s and early 90s, is a priori high-quality and that it is possible to use these audio components without wasting a lot of money on there will be a “vintage” audio system, what to sound, similar to the richness of the path of the day.

Let’s try to understand this theory. There is a piece of truth here - at the meaning of the hour, the very origin of the commercial sound fell. Programmers and correctors for creating vinyl, magnetic recording devices have reached the perfection, digital devices have appeared, and even a lot of models of really bright power-assisting devices have been produced. That's all true, except for the nuances :)

At that time there was no official category of equipment for Hi-Fi and High End; in fact, the products consisted of both budget components and even more expensive ones. If you don’t take into account the most affordable and exclusive models, and if you see the smart middle class, then the range of prices is still striking: $300–2500 per component. And if you realize that $2,500 in the mid-80s is just a huge pittance, then it becomes clear that nothing has changed since that hour - a clear sound, as if they were costing dearly, so they are costing dearly at the same time.

With the advent of online auctions, Japanese and European technology was used in a great stream in search of new rulers, and a significant part of it came directly to us, to Russia. Initially, for a very low price, a lot of exclusive and initially expensive equipment was put up at auctions, but it was not the case that the market had put everything in its place - the Vlasniks, which are selling stolen equipment for symbolic prices. pennies, resellers have changed en masse, trying to avoid making good money on this. The rulers themselves quickly realized why and how much.

As a result, the versatility of budget components has become such that, in order to support the current drinking of Vinyl, there is a need to formulate a new phenomenon about gvintage among the middle class, in order to present the consumer goods of quiet rocks as an equivalent to the current high-class audio components. It is necessary to say that successes in this field have been achieved, and what is meant by the concept of “vintage”, which previously meant little expensive and high-quality components in an advanced technical and cosmetic plant, now for the most part means be it budget junk for 30-40 years. It's weird, but it's a fact. Of course, vintage vintage items are nowhere to be found and are not available on the market, but are available at a low price.

What are the differences between budget and top-end components of the golden series of audio? In principle - everything. A large number of installations of components, high-quality materials, circuit design, etc. For example, we will look at two boosters from the 80s in different price categories: the already popular “vintage” power booster Dual CV-1460, which costs about $400 per hour, and the very expensive dual-block Onkyo Integra P-308 strength booster + Onkyo Integra M-508 strength booster ( 800 $ + 1500 $ per day). All of these devices are not rare and are often found on the Internet auction sites and in audio equipment stores.

Pіdsiluvach Dual CV-1460

If you believe what is written about this beauty in RuNet, then you, purchasing Dual CV-1460, become the owner of the “legendary” vibration, which operates in “pure class A”, with high output power (2x95 W at the current level) 8 Ohm) i will ensure “Vinyatkova brightness of sound”, equipped with an “excellent” corrector for vinyl. Now let’s look under the cover, carefully adjust, listen.

Integration booster Dual CV-1460

It is revealed... It has an absolutely budget-friendly design with the same equipment as a music center - cheap potentiometers, spring connectors for speakers, etc. There is no way to block the AC block - the replacement of the 3.15 A igniter in the sound circuit of inclusions is a 3.15 A - if the end cascade burns out and a constant voltage appears at the output of the ROZUM, then the AC will be lost, if the ignition is caught on fire earlier, lower the bass dynamics. Miraculously, this is encouraging :)

Integration of power booster Dual CV-1460 with removed top cover

With further development of the design, it appeared that there was some doubt about the validity of the stated parameters - those indicated in the passport satisfied the output strength of the reinforcement “forever” does not fade. There are two reasons:

1. The lancus has an AC connection with a nominal rating of 3.15 A, which indicates a maximum output power of 80 W on an 8 Ohm speaker. If you use 4 Ohm AC, the speakers will burn at half power.

2. Standard cooling radiators may not be able to supply the required amount of heat - their heating area is too small.

Let's look at "class A". Naturally, it is immediately clear that with such dimensions we cannot operate in “pure class A”, since the output power of 95 W per channel can dissipate heat of approximately 1 kW what a shame. Checking the service manual for adjusting the flow calmly, it appears that it will become as much as 3 mA! The booster actually works in class B, or “Dual class A”, which is the name of the basic circuit design technique that allows the transistors of the end stage to operate without commutation problems at a very low level calmly, only in general . A similar circuit design under the name “New class A” is available at Technics. Practical deception, then no, and class And no - it was very correctly guessed.

Further, we hear this “legendary” booster – the sound is soft, it doesn’t hurt the ear, but the hidden musical effect is even modest, the stage is flat, a little wider behind the speakers. On folding compositions, the porridge does not work, but it cuts through all those requirements that require you to properly create a musical fragment. Microdynamics are simplified, the sound is poor. The “wonderful” applied corrector for vinyl will sound completely different, which is not surprising for a circuit using one op-amp with a RIAA correction loop at the gate.

Nothing special, standard for a budget device of all hours. You can listen to this music, of course, but you can’t talk about the high intensity of the sound and music.

Set Onkyo Integra P-308 and Onkyo Integra M-508 (200 W\8 Ohm, 290 W\4 Ohm)

These are not the newest models of this series, and also the P-309+M-509, with a starting price of $6000 (in the 80s) and a total of 41 kg of cargo, but we will write about those that we have watched and heard especially.

Front booster Onkyo Integra P-308 and end booster Onkyo Integra M-508

This double-unit of equipment is inconvenient - a single mono design, including separate edge transformers, a power-intensive power supply, three pairs of output transistors in the end cascades of the skin channel, with a total current of 300 mA (class AB). The photo shows that the equipment and design of the Onkyo Integra P-308\M-508 is seriously different from the budget Dual CV-1460. I don’t need to be a fakhiv to understand this, I won’t get bogged down in technical details and will move straight to the audition:

Sounding softly, unprepared, the device will reach the deep stage, going beyond the placement of the speakers, the sound will not be connected to the speakers, the mind will sound emotional and has a high musical distinction. The parts do not lose greater strength. This little one doesn’t tire of hearing, but one wants to hear.

So, Onkyo Integra P-308\M-508 is a good booster, although it does not fall into the main category - the middle class. Of course, there are more recent models. This is where, in my opinion, true “vintage” begins.

End strength Onkyo Integra M-508 with removed top cover

However, the only devices that can be called “world” are those that, unfortunately, do not practically exist in the untrained technical and cosmetic industry, which, unfortunately, does not exist for auctions. Most vintage items will require not just repairs, but rather technical restoration, and with every step of the way the situation is steadily deteriorating (it’s still entirely possible to find out the best way). The axis here is where a new problem emerges - the extent to which the technology you have acquired has suffered during the time and the minds of the previous ruler.

It is often possible to create a unique arrangement behind the internal structure of blocks and assemblies, so that the device has been stored more than once in a place that does not burn, such as a garage, basement or balcony. I respect that if there is a trace of corrosion on the case and the internal chassis of the booster, and you can see the blackened solders on the boards, then it is not clear to make a purchase. In some cases, restoration will be much more expensive, but in extreme cases, repairs may be beyond repair.

Since it is important to get a device that is always pleasing to the sound, and not regularly disturb the mood by going out of tune or with countless other problems and flaws, then you need to start working on the income for the auction (the situation may reveal We are proud of the statements), and then find a qualified specialist who Get your new audio component up to speed. This procedure is expensive, there are not a lot of such fakers, just to say the least.

Then there is a lot of equipment that is already sold in Russia with the sign: “Prevention and adjustment of all modes for devices has been completed, according to the original service manual.” As practice shows, the number of really refurbished and customized vintage devices offered for sale is quite small. It’s not good for him to rely on this. The reason is simple - it is a difficult and expensive procedure, as there is a greater risk of the virus and it does not make sense to carry out the audio, since the audio was added to the auction for resale. Rest assured, all this “prevention” is reduced to a banal mast of regulators and remixers, so that the bugs and clattering in the speakers are not seen when they are shown to potential clients. In this case, minimally necessary steps are taken so that they do not require time-consuming expenditures for completing a service manual, disassembling components, performing adjustments, etc.

Varto notes, melodiously, that not everything, including the top reinforcements of rocks of yesteryear, initially has a small sound. Quite a few of the not-so-distant siblings, which sound bad, have already been released. The buttstock can be aimed at the Revox B-251.

Integration booster Revox B-251

Whose booster has on board a powerful pulse life block, digital regulation of the intensity and sensitivity of inputs, and electronic switching. The result is a pure, insightful sound, but completely lifeless and numb. The picture is flat, there is no scene at all, the sound of connections reaches the speakers. The parameters for this are high. One thing I know about adding Revox B-251 is just one thing – the stand of Revox components doesn’t look like anything else, and there’s nothing else to match the design.

It comes as a surprise, of course - the use of the Technics SU-V10 booster (not to be confused with the V10X - a completely different booster), which cost $900 in 1982, I don’t sacrifice anything, but I’ll change it anyway є double-block monster Onkyo Integra.

Integration booster Technics SU-V10

Ale tsiyu model Technics know in a decent place and buy a plant practically unprofitable. Once you get your head around the world of vintage auctions, you can soon notice that older models are priced richer than others and go under the hammer, having already appeared in public on other sites x. There may be different reasons - some sound good, others are easy to repair, others are extremely rare.

To summarize what has been said, the basic result is this: a truly clear vintage booster, which can be found in a dedicated technical and cosmetic shop, adjusted by a qualified fachist, only from the service new documentation, we can completely reduce the current competition to current devices of a high price category, otherwise the resulting profit will be minimal . keep it clean. And the budget boosters of these rocks can successfully make do with their current classmates. Its main advantage over the new one lies in the fact that, as a rule, it has a detrimental effect on the sound of electronic switching and regulation, which simply infuse almost all new minds.

The article contains my special thought, based on a wealth of practical evidence, but it may not coincide with the thoughts of other people and I don’t see anything terrible in anyone.

First publication of this article

Z povagoyu, O. Shamankov ( Prophetmaster)

From this series of articles we can learn about the greatest boosters, according to experts: Peter Breuninger, Neil Gader, Robert E. Greene, Robert Harley, Dick Olsher, Harry Pearson, Paul Seydor, іJonathan Valin.

Dynaco ST-70
Powered by Avery Fisher's 500c, ST-70 creations by David Hafler set the sound bar for the entire American school. Released in 1959, model ST-70, with a limited edition of over 300,000 examples. Incredibly, its clean, spacious sound is still relevant and can compete with a lot of current boosters.

McIntosh M.C.3500
Since the MC2505 has lost all trace of its blue indicators, many people regard the MC3500 as the most powerful booster, if ever vibrated. It was released in 1968 and its commercial name was MI350. Having turned over any booster at that time, it was very powerful 350 watts of output pressure. The boot version of the MC3500 booster introduced McIntosh to the leader of the world of audio.

Phase Linear 700
Yshov 1970-th rіk and Bob Carver (Bob Carver) owed their talent to transferring a new product to the market, which created its own segment - high-class mass supplements. Musicians from rock bands used ice to put it on the top cover of the booster in order to prevent this 350-watt booster from overheating in critical modes. I recommend the first series models.

Krell K.S.A.-100

A powerful first transistor High End booster. It was born in 1980 and whoever could have allowed the KSA 100 model to make Krell one of the largest brands. Dan D'Agostino discovered that transistor boosters could make music. To this day, Krell sets standards with its products made with the highest level of brilliance and unparalleled sound.

Mark Levinson M.L.2
This is supported by the creations of John Curl, allowing Mark Levinson to become a legend in the audio world. 25-watt ML2 monoblocks are Mark Levinson's first power amplifier, designed for working with acoustics that have a very low impedance. Such as the legendary HQD systems (Hartley, Quad, Decca Ribbon).

Audio Research Reference 610 T
In the 1960s, William Zane Johnson began manufacturing and selling upgraded Dynaco ST-70 engines. The absence of transistor boosters was created in the 70s. Prote a tube D70, born in 1983, once again setting the level of power of Audio Research boosters. In 1995, Johnson created a product that has become legendary - the Reference 600. Having been integrated into the 610T model, with 600 watts of power, there is no equal.

Conrad Johnson Premier One
Released in 1981, two years after the release of the first Conrad Johnson MV75 booster, Premier One became the first tube super booster. They are powered by Audio Research's 50- and 75-watt power amplifiers, with an output power of 200 watts per channel. Vin is still popular among collectors (including me).

Carver Silver Sevens
Carver (Bob Carver) bought output transformers in the 1960s and nearly twenty years passed before he began to power his world on their basis. Carver's boastfulness is still heard. He shocked the world with his expensive (17’000.00USD) and esoteric lamp booster. This booster has a power output of 375 W per channel. Available on four different chassis and equipped with fifteen (!!!), per channel, KT88 lamps! Before speaking, I was lucky enough to hear the first copies.

Audio Note Ongaku
Vіn shock audio light. Submit 60’000.00USD! In 1988, a single-ended booster by Hiroyasu Kondo was born with an output power of 27 W, setting a record for high-priced audio components. This was the first serial power supply, in which components (transformers, capacitors and components) were hand-made.

Cary Audio CAD-805
This is the year of the sublime death. Cary CAD-805 booster by Dennis Had by turning the single-ended boosters onto the audio magazine covers. He was responsible for assembling McIntosh powertrains and became the founder of the phrase “single-cycle magic.” Pіdsilyuvach has been carried out since 1992.
