Bi-Amping B&W 802N - Who's doing it and with what?

What performance inprovements are you looking to accomplish?

Most likely the addition of a second amplifier will also require an outboard crossover device (and another interconnect)so that gains can be properly matched. Even if the Wadia can drive single ended output along with the balanced output you have connected to the Krell, I think it would be hard to find a single ended input amp with high enough gain to matched the balanced gain.

For fewer dollars, you may notice an improvement by adding a preamplifier instead. Several magazine reviewers have recommended the use of a preamp to get the last bit of performance out of the Wadia.

I agree with Alexanderj's suggestion. Your FPB200C would give you a better performance all the way around if you will add an active preamp, perhaps a tube for that added "life like" sound... I think direct connection would give you the cleanest sound but I prefer full bodied sound from my tube preamp driving FPB and N-802s.

I'm using 4 Monarchy Audio SE-100 Delux' to drive my N802's. I would have preferred to go balanced, but my processor won't allow that. Single ended is just fine however, and I don't have to worry about gain variations with this configuration. At any rate, N802's love to be bi-amped. If I was using these in my music room, I would have bi-amped them with Electrocompaniet amplification, which is what I use in my music room.
