Pdn: As to max power ratings and amp capacity - probably would not be a good idea to crank up a 380 watt amp to the max driving the speaker, but, so long as the amp is not continuously driving the speakers at max there is no problem. My guess is that 804ilawood drives the 1080 with a signal that does not push the 1080 to overdriving the speakers. Having this 'reserve' capacity, so to speak, goes toward not driving the amp into distortion. In short -an amplifier that is capable of providing more power than the speaker can take is actually a good idea.
B&W 683 floor standers
I'd like to hear from those who own and play these on a regular basis. How do you like them overall? Are they too boomy at times? What size is your room? I'm considering them as an upgrade from B&W DM603-S3's. My room is moderate in size (2400 FT3) with 2 openings to hallways, no doors. What do you think? Do they produce good slam and punch at the low end? My room is bass starved and needs powerful speakers in this dept.
