Which Mc better Mid/High performance in BiAmp set up?

Thanks..
When I bought this pair of 801 Nautilus in October (used) I saw they needed a special little wire to hook up the terminals which i didn't have..looking into more reviews and more deeply it seems the speakers (from what i read), were designed to be BiAmped..The guy I bought speakers from had a couple of Tube Amps on the Floor & I think another Amp in his rack.So I figured that must be so.
So till this day speakers sit there wrapped up and unconnected as it has taken me this long to decide and bring myself to sell my unused new in box MA6500 Integrated Amp to buy the other amp required for biAmping.I never even knew what BiAmping meant and still barely do. I thought the alternative was just getting another Amp & run em in Mono..but I dont really need any more power. The 801F's i've have had since 1987 and about to replace,were much more inefficient but way loud enough with the 270 Watts per Channel.
Hopefully the new 801N is actually an upgrade to the 801F cause they sound pretty much like the most natural accurate speaker Id ever heard.

Given the above, you really need to just hook everything up and see how it sounds. You're not going to hurt anything. Just connect a pair of speaker cables to either the top or bottom set of binding posts on each speaker. I usually use the top, but it really doesn't matter. And then just jump the 2 pairs of binding posts with small pieces of speaker wires. You're not doing anything that's wrong, or will harm the speaker. If you were to ask B&W, they would tell you that fine to connect them this way. Then, I would just unbox your MA6500 and let everything warm up and break in. Spend some time with it and just see how it all sounds. I've heard B&W with McIntosh many times, and while I don't really care for B&W, its one of the better matches I've heard for those speakers.

As far as using separate tube amps for the highs, its still a bad idea. Its like buying an EQ with only 1 setting. If it doesn't work, its becomes a trap. You'll just keep buying stuff to try and make it sound OK. The tone controls on your MA6500 will be far more effective at dealing with the highs. If you take the time to hook all this up and give it a chance, I think you'll be pretty happy with the results. After you've had a chance to spend some time with your system, assess where you think the system needs improvements, and make whatever adjustments you need to (if any). More likely than not, I think you'll get away with spending little, to no money.

Thanks Z..
The MA6500 Integrated Amp was not for this it was for a separate system we were going to do in another room hooked up to tv..never used it once we got a tv (5 years later) and realized we didn't like anything they play on TV ..nor the $100 cable bill,and so we dont need MA6500.
We are very slow in doing things : (
We use the McIntosh C29 PreAmp and a Mc7270 for the stereo.

I bi-amped my 801Ns using MC1000 for the low end and an MC2000 for the highs. The tubes really smoothed out the high end in my case. However, the lower power held down the MC1000's a bit. Also, you may need an amp with volume controls. I had to pad down the MC1000 amps as the bass was overpowering the highs. This was, by the way, after McIntosh told me that the two amps should match.
As always, YMMV.

I had B&W 803ds and they sounded better to me with the more power I gave them. Had one MC352 switched to 2 MC352s bi-amped and this was better. Then went to MC601 monos. This was best for me. My experience is that B&Ws love lots of power.
