I agree that upgrading beyond the HiFace for a PS DLIII is probably not a wise investment. I used this combination in the past. Then went to a Bryston BDA-1 with Audiophilleo 2 W/Pure Power. That was 4 years ago and I still use it today. Recently I purchased a used Wyred4Sound DAC2. I haven't had a chance to do a critical compare against the BDA-1 A2PP combo. I suspect they will sound different, however one may not be declared better across the board.
I do believe converters have a place when paired for computer purpose with many of the older hi end DACs known for having solid power supplies and output stages. Buying a new DAC today, to include use with computer audio, I would look for one having quality USB implementation built in.
