^ Discussion of practical design features that can provoke or lessen slew-rate limiting and transient intermodulation in audio amplifiers can also be found for example in chapter 9 in John Linsley Hood ‘s ‘The Art of Linear Electronics’ (Butterworth-Heinemann, Oxford, 1993). Musicians with unique performance needs and/or a need for very powerful amplification may create a custom setup with separate rackmount preamplifiers, equalizers, and a power amplifier mounted in a 19″ road case. For some years following the introduction of solid state amplifiers, their perceived sound did not have the excellent audio quality of the best valve amplifiers (see valve audio amplifier ). This led audiophiles to believe that “tube sound” or valve sound had an intrinsic quality due to the vacuum tube technology itself. Up-to-date pricing and reviews for hifi power amplifiers on the market can be found at the power amplifier reviews website.
For this reason, the design choices made around the output device (for single-ended output stages, such as in single-ended triode amplifiers) or devices (for push-pull output stages), such as the Class of operation of the output devices is often taken as the description of the whole power amplifier. Key design parameters for audio power amplifiers are frequency response , gain , noise , and distortion These are interdependent; increasing gain often leads to undesirable increases in noise and distortion. Three rack-mounted audio power amplifiers used in a sound reinforcement system.
In the 2010s, there are still audio enthusiasts, musicians (particularly electric guitarists , electric bassists , Hammond organ players and Fender Rhodes electric piano players, among others), audio engineers and music producers who prefer tube-based amplifiers, and what is perceived as a “warmer” tube sound. Hitachi was the only LDMOS manufacturer between 1977 and 1983, during which time LDMOS was used in audio power amplifiers from manufacturers such as HH Electronics (V-series) and Ashly Audio , and were used for music and public address systems 4 Class-D amplifiers became successful in the mid-1980s when low-cost, fast-switching MOSFETs were made available. 4 Power MOSFETs were soon manufactured by Yamaha for their hi-fi audio amplifiers.
The triode vacuum amplifier was used to make the first AM radio 2 Early audio power amplifiers were based on vacuum tubes and some of these achieved notably high audio quality (e.g., the Williamson amplifier of 1947-9). Amphion manufacture power amplifiers to match their own range of passive monitor speakers, and when I first reviewed the monitors in the magazine I was also loaned one of these. UK hi-fi brand Linn have a range of power amps, many of which include balanced inputs, that come up for sale regularly, and often for very reasonable sums.
This Norwegian powerhouse amplifier (375Wpc into 8 ohms) combines the brute-force bass control and dynamic impact of a dreadnought design with a midrange and treble refinement reminiscent of a single-ended triode amplifier. Capable of driving most speakers and resolving musical details well, the D200i gives music lovers a healthy portion of what Gamut’s even more powerful and highly resolving M250i mono amp sounds like, but does so at a much lower price. This mono amp offers a lot: tonal neutrality, dynamic control, expansive soundstaging, fine resolution, plenty of power reserves, and great musical expressiveness.
A 75Wpc hybrid power amplifier using KT150 power output tubes, this latest addition to Audio Research’s Foundation Series, the lowest-priced products in the Audio Research lineup, shares a common styling theme with the rest of the series. Here you’ll find integrated amplifiers, preamps and power amps of every shape and size. If you want great sound from a separates hi-fi system, you need to choose a top quality stereo amplifier.
Stereo amplifiers aren’t as simple as they used to be. The days of equipping them with just analogue inputs and outputs, and a pair of speaker terminals, is now no longer the norm. Such amps can deliver stunning sound but can be harder to pair with speakers based on statistsics as a lower power rating may not equate to the same power rating on a solid state design. Most of the power amplifiers we offer are made for stereo use and suitable for driving a pair of speakers.
Using an individual power amp and pre amplifier is considered the pinnacle of audio and most premium systems and no expense spared hi-fis use separate power and pre amplifiers. There’s also the option of bi-amping, which requires at least two stereo power amplifiers (unless you have a multi-channel receiver with spare channels) and some more cables. Some stereo amps also have two sets of speaker terminals – usually labelled zone ‘A’ and ‘B’ or ‘1′ and ‘2′ – which allow you to run two pairs of speakers at the same time (in different rooms, for example), although this can have a detrimental effect on performance as essentially the amp’s power is being shared multiple ways.
All stereo amps have line level RCA inputs, which can be used for all the usual sources – streamers, CD players and so on. One of those RCA connections is sometimes a phono input, designed specifically to be connected to a turntable and handle the very low signal levels and extra equalisation required for such a source. Zanden Audio SystemsModel 3000 MkII line preamplifier and Model 9600 MkII mono power amplifiers Zanden Audio Systems remarkable line of valve-oriented electronics are not exactly unknown to us at Hi-Fi+. A phono preamp/phonostage will bring the cartridge signal to ‘line level’ and make it compatible with the integrated amplifier’s line inputs.
In addition to these formats of a traditional amplifier, more and more headphone amplification units are being designed and engineered by quality brands as the demand for high-end personal audio increases. An integrated amplifier features both the power amplification and preamplification elements combined into a single box solution. Amplifiers typically come in three formats; a power amplifier, a pre-amplifier and an integrated amplifier.

The arrival of the new Ultima power amplifiers from Chord Electronics – at £30,000 apiece in either silver or black, along with the matching (and similarly-priced) Ultima preamp – suggests so. After all, their rated power of 780W/8ohm load is just north of the 768W claimed by Naim’s ‘Statement’ NAP-S1 monoblocks HFN Jun ’15 – a target vaunted as ‘one horsepower’. At first glance, one might be forgiven for wondering what’s going on here – after all, California-based Constellation Audio already has a Centaur II stereo power amplifier on its books, selling for a not inconsiderable £48,000.
Music came from vinyl, and its meagre output was such that plugging it directly into a power amplifier would have produced all the power, as Captain Blackadder once said, of an asthmatic ant. If you only have two speakers, a stereo power amplifier will work perfectly. Most power amplifiers on the market offer two channels.
Stereo Power Amplifier- These can support two loudspeakers at the same time. Power amplifiers are classified according to the number of channels they have. If your loudspeakers have a power rating of 200W, then your amplifier should produce 400 watts with the same ohm load.

Ultra-efficient, cool-running and responsive, Linn’s power amplifiers set the standard in high performance amplification. Audiophile’s amplifier or high fidelity amplifier is a amplifier that reproduces music that sounds identical to the sound on the recorded source.
However: newer power supplies and lighter components mean this rule is a lot less hard and fast than it used to be. When it comes to things like power amplifiers, it’s still very much applies, but in the case of integrated amplifiers, you can see it as a guideline more than anything else. If we had to pick the amplifier with the best DAC, we’d probably go for something like the $1,195 Para sound New Classic 200 Integrated , which offers absolutely superb conversion. Your audio exists as ones and zeros until it passes through one of these, whereupon it is converted into electrical signals that are used to power the speakers, which then give you sound. Be sure to visit power amplifier reviews for the best hifi power amplifiers on the market to buy.
Sure, you’ll get an amp that bucks the trend – very obviously, something like the $57,000 D’Agostino Momentum Integrated is going to be better than the $599 PS Audio Sprout100 – but for the most part, what you’re paying for as the price increases is more power. At its most basic level, the stereo amplifier takes this source sound and makes it louder, using the current from its power supply to increase the overall volume of the sound.
