Превосходный DAC для Rock музыки завораживающее звучание. Новинка Сентябрь 2013!

Dedicated Discrete Diamond Difference design  DAC
NOS design applied up to 96K support
4pcs PCM1704UK (two-two parallel)


 It is close the PCM1704UK chips out of stock, so we design the NOS-1704 as the final version musical DAC built in PCM1704UK .
         The NOS-1704 had applied the NOS + Diamond Difference combo design which is had consider the best musical designs.
         Some years ago we have build different NOS DACs , TDA1541, TDA1543 sound too warm but lost detail .
         The NOS-1704 sound not very warm but  smooth , have not lose detail and reduce dynamic, the most important is it still have black background  .
         While you decide place the order please ensure the NOS DAC  characteristics.
