The A-DACII is a digital converter with USB and Spdif/coax and Toslink inputs.
The digital signal is up sampled from 16bit to 24bit and the frequency response is increased from 44.1 KHz to 192 KHz. This will reduce the noise floor by more than 10dB so that music signal previously masked by the noise now will stand out and amplified, and high frequency overtones will be reproduced without any distortion..
To achieve maximum cancelation of distortion and low frequency noise, the amplifier stage is fully balanced from input to output. To further reduce the distortion and improve linearity, all transistors are matched.
This reduce the need for high negative feedback and thereby avoid the traditional "transistor sound".
To avoid influence from the noisy computer supply, a separate DC power is supplied.
This also reduces the distortion from the USB system.
A digital Spdif/coax output makes it possible to connect other digital products to the unit, such as home theater system.
