I found the Beresford Dac 7510 to respond well to better Transports and digital cables. Each time I tried a different one the sound quality changed. The best results were with an Audio mecca Mephisto mk2 (a dedicated French design from TT maker and designer Pierre Lurne).

The nub of my experience was that a cheap transport will not IMHO/E reveal the full potential of the Beresford Dac. Now the current one might not be the same...I haven't tried one yet.
