Thanks for the information Kilian.ca
I have noticed since I've had the 818 that my front soundstage has been "weak". The Onkyo 805 that I had before drove my Kef 104/2's and previous JBL center well. The front soundstage was well presented. I know the 805 had a very serious amp section and the 818 not so much. While watching a couple blu-rays this evening with the "new to me" B&W's and after a proper Audyssey calibration the front soundstage was still on the weak side. Better defined but still somewhat weak. I don't believe this is an Audyssey issue as driving the fronts for music requires a bit more throttle. The B&W's are approximately as efficient as my former fronts and center at +/- 90db. Perhaps this is where the external amp would help if I do as you mention and have it run the front soundstage 3 speakers and the receiver handle the rear speakers.
Decisions, decisions....
