Jayboard,
The BP25DA uses the same DACs as the Bryston SP-1.7 and adds jitter control. On www.audiocircle.com there is a Bryston/PMC Owner's Circle where the sound quality of the SP-1.7 and BP-25DA have been discussed at length. Although I do not own the non-Bryston equipment that your are comparing against, several posts have been made at audiocircle that compare Bryston with other DACs. The audiocircle forum also has a lot of information on the BP25DA's successor, the BP-26DA. I personally use a cheap Sony DVD player as a transport and use the DACs in my SP-1.7 for 2-channel music. The sound quality on good recordings just blows me away every time.
