Yes, I was doing Roon/Amarra for Tidal>Mac mini via USB>PS Audio PWD.
Yeah, I don't completely understand why there's even a difference at all with any of software client. I get why a DAC would make a difference, but only sort of get why the software client would. Don't really know.
I like Roon a lot, except for the crazy price. IIRC, they use Meridian's audio engine? I thought it sounded very good, and in one night, rediscovered a bunch of music both in Tidal and in my NAS collection.
Still, because of the price, I actually had planned on doing the trial then cancelling before being charged. Silly me, I forgot to cancel and then saw the charge come through while I was on vacation. Can't say I was very upset, though. I was actually kind of glad! I think I know what Freud would say about that... [emoji12]
