Hello
I currently have the 801N and 804N but have had several B&W 800 line of speakers. All sounded better with more Power (with in reason). However the biggest Gain I have found is to BI-AMP. Your 802N should do real well with around 200 to 250 X 2 EA speaker BI-AMPED. I am currently BI-AMPING MY 801N with 350 X 2 EA speaker. I simply use 1 AMP for each speaker. To me BI-AMPING the B&W 800 line really makes all things better. You seperate the crossovers, let the mid range open up and extend the bass. I find more detail more depth and a larger sound stage. You could use more power to control the Bass driver and less for the mid and tweeter. But amp gain matching and other promlems has caused me to just use a single 2 channel amp for each speaker.
Good Luck Bob
