I was looking for a new DAC recently and auditioned Onyx and Aqua La Voce in the same system. Very, very close. I could live with either. In the end La Voce won by a small margin sound wise and due to a clearly better USB input and its modular upgradable design. Both are R2R, both have highly acclaimed designers. La Voce is the best DAC I have ever owned. The old Reimyo 777 comes distant second. DACs have progressed in recent years, I was surprised to be honest.
