I'd bet the 307 will run the M80s without ever needing more. While I am firmly on the side of more power pays dividends, the B&K line is not the typical Sony or Pioneer we have this debate over. I have heard a B&K AVR (not sure which #) run a pair of the largest electrostatics Martin Logan Summits (91db 4 ohm)...never heard a peep that was not supposed to be there.

Use that money to nail your surround setup, your bang for the buck is tenfold compared to beefing up the B&K path. I would go for QS8s, period. The image improvement over direct radiating design is dramatic - at least in my small HT. Perhaps in a huge room you could achieve the same with M50, but I doubt it.

The Qs are the best audio values I have found.
