HT vs. stereo pre-amps again

I've currently got both a Sunfire Theatre Grand MKII and a Perreaux SA3 stereo preamp, both of which are feeding the amp that powers my fronts (bryston 4B-NRB). It's an inconvenient setup (neither has a pass-through). Several threads here have discussed whether there are HT preamp/processors which can compete with a good stereo preamp, and if I read them correctly, the consensus is probably not. Bryston has a new processor out (SP1) which has completely separate analog and digital sections. Anyone have any experience with this unit? It's analog section is just their BP25 preamp. Alternatively, anyone have a surround processor (I'm looking maybe CAL CL2500) that really keeps up with a good analog unit?
