Etalon Sound presents a technological breakthrough, based on the best and proven technologies and the latest innovations.

Etalon Sound creates everything you need to realize your dream of a perfect sound: DreamDac, TrueAmp, Acoustic systems. The quality of our equipment is guaranteed by the only possible objective method of sound evaluation. It involves a World famous conductor, who creates Music and who is an impartial Sound connoisseur.
We believe, that only the One, who listens to Live music daily with all its fullness and sonic variety, is able to make an objective assessment of the sound quality of any audio system.
The orchestra conductor hears each instrument, each shade and nuance during a concert, and it is the One, who is the most objective in assessing the sound reproduction. To get an unprecedented assessment, which can really be trusted, we invited not just an experienced and famous, but one of the most celebrated conductors of our time.

A normal (unbalanced) signal is transmitted by two conductors. One is a signal conductor, the other is a ground one. This signaling method is diferent by complementation simplicity, but it cannot withstand interferences.

In contrast, a balanced signal uses three conductors: two signal conductors (direct and inverse), and one ground. As the result of subtracting from the direct signal of the inverse one, the phase interferences, induced on such a line, are compensated, and the useful signal is increased in amplitude twice. That is why a balanced connection has two main advantages: the ability to transmit signals over long distances (200 meters or more) and increased interferences immunity. These features of the balanced connection explain its use in professional and consumer audio equipment of high class.

A third advantage is much less known: balanced circuit can significantly reduce the harmonic distortion a properly assembled balanced amplifer circuit harmonics can be reduced of 10, and using specially selected elements – up to 100 times! We know, that many manufacturers use a symmetric XLR interface. However, upon closer inspection, it often turns out that it is rather a formality. And the components, declared to be balanced, substantially are not. The existence of balanced inputs and outputs does not guarantee that the scheme located within is balanced. Rather often after the input the signal is converted from balanced to unbalanced, amplified or somehow still treated by the asymmetric circuit and before the output is converted again – from unbalanced to balanced. As a result, this approach negates all the advantages of a balanced circuit design.It should be noted that not only amplifiers, but all components, manufactured by Etalon Sound – DAC, TRUEAMP and others – are of balanced circuit.

You can buy separately any of Etalon Sound audio component you are interested in but it is better to order a full set of compatible bespoke devices adjusted to your conditions to provide true soundstage and imaging.


However, to realize all the ideas embodied in our equipment, you ought to have a complete set.
We ensure that the quality of the sound with our audio set is fully consistent with declared high level. Within other audio systems it is dificult to achieve a proper matching of components. And components need to comply for proper operation of the equipment. 

For example, our amplifers are fully compatible with speakers, and the input of the amplifer, in turn, is agreed to the sound source – DAC. 

‘And while a reproduced sound will never be the sonic equivalent of a live presentation, coming somewhere close is a profoundly more enjoyable way of listening to music.’ – Paul Wilson

“My work is to understand and to convey the composer’s intention. My pleasure is in the beauty of the orchestra sounding. I can reach it during the performance. But it is very hard to pass it to listeners outside the hall.

Aſter “Manon Lescaut” rehearsal at the Bolshoi Theater, I was asked to evaluate the opera recording. I really liked the naturalness of the sound and the sense of presence in the hall. I again felt myself behind the conductor’s panel at the Bolshoi Theater.

Thanks to Etalon Sound equipment I have the opportunity to visit any theater in the world. Now all the brightness of emotions from live music is available to you with the sound quality of Etalon Sound.”
