This was the most difficult and the most rewarding review to make. It is a first when I can call the same DAC slow and fast, hard slamming and easy going, super detailed and rolled off. Since R-2R DACs are relying a lot on the FPGA code, the manufacturer is basically telling it how it should sound, not the other way around as it happens with delta-sigma ones. If you like to tailor your sound or if you change your acoustic chain quite often and worry about system matching, then Audio-GD R7 seems like a perfect digital source to own, it is really a chameleon and a system matching God.
