Ditto. I tried some spare B&W Matrix 802 floorstanders in place of wall-mounted Matrix 805s. Never bothered to swap back. What you heard and experienced George & Fanz is the same for me.

For anyone going for large analogue surrounds, don't skimp on the amp. I had been using an old integrated but when I had a spare 557 I slipped that in and once again, never looked back.

If/when I go back to 7.0 from 5.0 I intend to find space for some full-sized side speakers.
