OP
I owned the middle tier CHORD products in the years past and after listening to the Denafrips, I made the switch. I did NOT own or heard the Dave
But generally, the CHORD has a distinct "house" sound. it's very detailed and too clear that others here say its clinical. IF that is what you are going for, then get the DAVE as it is their flagship. i have not heard the PS audio, but they do have a trial period. I highly suggest that you take that into consideration.
As others have posted above, some have posted terrific experiences with Chord, and I believe it. It's all about system Synergy and what you want to hear.
