@vwquest,
Congratulations on your upgrade. While I don’t own 802N but I have some experience with bi-amping my 800D2’s. As you know, 800D’s is a slightly bigger speaker and best driven with a higher output Amplifier.
To further add to @rhljazz point, simply adding two separate brand of amps would not yield the desired results. Did you check the gain on these amps? I have tried and failed to achieve desired sound by feeding the bass region of B&W’s with a Class A/B amps in bi-amping mode. The amps were McIntosh 601’s mono. The MC601’s just didn’t had the enough juice to drive down the bass with authority. I tried this with McIntosh MEN crossover in the chain. However, 601’s performed admirably well when they were bi-wired to single speaker.
If you must bi-amp, try a Class D amp with at least 400W in 4ohm load spec for bass and put MC252 for mid’s and high’s duties. The MC252 is a very clean, detailed sounding amp. It will drive your mid’s and high’s fabulously. I would recommend trying Red Dragon S500 or Bel Canto 600M’s to drive the bass of your 802N.
If you chose not to bi-amp, then I would suggest the MC252 in a Stereo mode with a one or two subs for desired sound.
FWIW, I end up pairing my 800D’s with ARC VT-80 and Merrill Audio THOR’s Class D mono’s and I can say unequivocally that my speakers never sounded so good. BTW, I am not using an external crossover.
Through the whole process, I was patient and knew the kind of sound I am after....the key is to be patient, most people gives up easily 😊
