I sold my PWD MK2 for the Reference 7.1. The PWD also sounded congested and small in comparison. I'd get the Master 7 if I were you. I owned a few Sabre DACs and they were decent for the money, but they couldn't touch what I have now. Also, I used the best computer transports with these (OR5+upgrades, MK3 JKSPDIF) since I know you brought up the concern.
