B W 802N how much power?

I am driving my 802s with Sonic Frontier Power 3s which is rated 220watt/ch. I find this power to be more than adequate. Don't forget that 802s are very efficient speakers (8 ohms). I have heard them being driven by a Lab 47 amp which I think is rated something like 7 watts, and I was blown away by the 802s' dynamic and its full bass performance. I don't know what type of music you listen to, but I have never turned my CAT preamp pass 9 o'clock on the volume knob (starts at 6 o'clock). These are my 2nd pair of 802s, I think they are really great speakers for their value and sound quality. Email me if you any question with these speakers. Good luck.
