To bi-amp B&W 802n or not

Erik,
The MC 252 has 250 watts per channel.  This is sufficient power for an N802 for music.  Adding another amp which the OP doesn't have other than the Carver plus a processor or external crossover doesn't guarantee results that would improve upon the MC 252 alone.

DRC,s have their plus and minus issues.  To me they are like a lot of the drugs advertised on TV.  The cure with attendant side effects is worse than the disease.

Proper room placement and room treatments when required are a better option.

Biwiring may or may not be the best option.  I am currently setup biwired but prefer my tube amp single wired with the supplied BW jumpers.  The OP should experiment with with what he has available first.

Biwiring vs Bi-amp vs Singlewire
Since you have everything on hand why not experiment and let your ears decide, its our hobby isn't it?

Thanks to everyone for you input.  I will give your ideas a try,

Before trying bi-amp try first to change the stock jumpers of the speakers with more quality hi-end ones you will be surprise how it can improve the sound.

Sorry but I don’t understand how you can bi-amp with McIntosh 601’s mono,
Mono is for one speaker and if you want to bi-amp speakers you need 2 mono’s for each speaker total of 4 mono’s for a pair of speakers ?
