Bartjo - I'd definitely go for the 7.1 option. As long as the speakers are fairly well matched, although the YPAO should iron things out. You'll also get Pure Direct mode thru your fronts which IMO sounds very good for 2 channel music. On another note, I was forced to use the Night mode the other day as I was watching movies late. It basically cuts out the really highs and the really lows but keeps the volume the same (ish). That means the neighbours don't complain when things blow up on screen. Quite nifty.
