I have an Apollo. Its a great CDP IMO. By far the best CDP for the money and a fair amount higher. I've heard Bryston's internal DAC, but don't have one in my B60. It really all depends on what you like. If you have both in your home, try it both ways. Bryston's DAC section may be better on paper, but don't be surprised if the Apollo's DAC wins out. In either Hifi Choice (most likely) or What Hifi, they stated that the digital out on the Apollo may give some DACs some problems. I can't remember what the cause of it was or if it can be corrected by a DAC like Bryston's. It was a while ago. I remember them saying the problem wasn't appearent with the analog outs, but was at the digital out. I think it was a Hifi choice shootout between the Apollo, Naim CD5i, Creek Evo, and a Shanling tube CDP, it that helps in a search of it.
Regardless of what reviewers or people on a message board say, try it both ways at home. None of us have your ears.
