Description
This device is a "combine" which means a device that combines functions of two individual devices. In this particular case it is a combination of a digital-to-analog converter and an amplifier for headphones. And we are deeply convinced that at the present there are practically no devices of the same level in the world. And here is the reason why - DAC1866OCU differs from the majority of combined devices existing in the world by the fact that there are none of devices embedded in our product simply for a checkmark. Usually (and almost always) there is an amplifier or a DAC in such "combines" is installed according to the principle "there must be something else", but the main emphasis is made just on one thing.
In spite of such products in DAC1866OCU we tried to make both components as high-quality as it was possible to achieve in them. You should come to our office and listen to it to estimate the final result. But still in this we should provide some basic information about this device.

MyST DAC 1866OCU

First, the DAC that is used in the device - multi-bit (parallel, R-2R), in contrast to the vast majority of converters. Specifically, this chip is 16-bit, which is somewhat "deficiency" from the point of view of the customary to "magic" advertising TTX delta-sigma.
But, on the other hand, 16 bits are more than enough to ensure that the human hearing capabilities are overlapped. Аnd, in addition, we can get transient characteristics fundamentally unattainable by any one-bit converters with the help of a multi-bit converter unlike delta-sigma converters.(For more details about measurements - on the pages of our forum)
And with full confidence we can say that no single-bit device will ever be able to compare with a multi-bit converter in working-off attacks, fast strikes, sharp sounds, etc.

MyST DAC 1866OCU

The loss in some quasi- multi-bit of delta-sigma converters is more than compensated by the attacks transmission capabilities of R-2R DAC, considering that sound attacks (as well as their attenuation) are an important part of the tone quality coloration.
Secondly. For the same purpose, the device isn’t used any "improvers - recalculating" type 16-24, 44-192 and other, other. In other words, the DAC in this device is manufactured according to the NOS scheme (Non Over Sampling). Because, the digital filters spoil the transient characteristics, which for us are much more important than the promotional mega-figures s / ch, etc., which, by the way, are already the same as for consumer mp3 players, as for stationary devices for thousands dollars. And the difference of which, rather changes the taste, but not really affects the quality.
So, the transitional characteristics are primary for us. Although, no one is going to forget about the other parameters. And in our case, the device “squeezes” everything possible and gives out a maximum, which in general can be obtained from 16-bit sound in general, and from this chip in particular.

Thirdly. The headphone amplifier has a power swing of 30 volts, which allows you to "swing" almost any headphones that exist in the world, with a resistance of 8 Ohm to 600 Ohm.
The amplifier is used the A.Nikitin regulator on the relay with 7 bits, giving 128 levels of loudness with "infinite stroke." This number of iterations is enough to accurately adjust the sound for almost any user, because the difference between the neighboring values is extremely small and often is almost the same on hearing.
