Someone in HF promised to compare The Audio GD
DAC 19 to Ares so chances are that there will be some info soon. Audio GD is supposed to be very good also but if we check spec the R2R ladder resistors in audio GD are 0,1%
precision (DA M1 modules)
but Ares has
0.01% resistors
and the top Denafrips models even use 0,005% resistor ladders.
