Thanks for the responses guys.
foreverhifi: I listen mainly to rock and I bought the pre with hopes of better sound. If I understand you're scenario, for 85% of my music listening I would be using my Yamaha receiver and amp. This is what I'm trying to get away from by picking up the preamp. Rock may not be as "pure" and "clean" as some other types of music, but it's what I listen to and it's the type of music I'm trying to make sound the best. I've put a fair amount of effort into dialing in the Bachs as best as the room and environment will allow. I went from everything < 90 Hz being handled by a pair of 12" woofers to a pair of 7" in the bachs. I miss the slam. I'm curious about your configuration option when you talk about bypassing the pre/pro and running the sub in parallel. If I bypass the processor how can I run the sub in parallel? If by using "speaker level" connections, you mean the speaker level connections found on the back of some subs, mine does not have them. If you have another configuration option in mind I'm anxious to hear about it.
Johnathanb: These are smaller 2way floor standers.
I'm content with the speakers I have and changing them is not an option right now.
