This is sort of a follow-up to my previous thread but contains 2 questions concerning B&W specifically. Hence the new thread. Some folks have indicated to me that they'd rather use the B&W 805's in the rear as opposed to using the B&W SCM1s. How much "OOoomph" will we be sacrificing by going with the wall-mounted SCM1's? (The fronts are a pair of 802's). Second question has to do with amplification. I had mistakenly read the Proceed "BPA-2" (125W/ch) as "HPA-2" (250W/ch) on the invoice so it looks like my dad bought the smaller amp to power our 802's instead of the bigger 250 Watts/ch. My initial reaction is that for a pair of speakers like the 802 (with a "recommended amplification" of 50-500Watts), we'd be much better off with the bigger HPA-2. That's my gut feel, but I am in no way a pro. Need some feedback/support/reassurances here before I make my case for a change from BPA to HPA!
