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

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.

MC1000's..?
You mean two 1000 Watt mono block amps with yet more power for mid/highs ?
And they (a pair of 801N)sounded better with all that running into them ?

Wbs/Bill..

This is what B&W said about my "predicament"

Bi-amping has been observed to improve the performance of loudspeakers, however the benefit will only be realised if identical amplifiers are used for both sections.

If differing amplifiers are used, as in your case solid-state 270w Vs. tube amp 75w, the overall timbre balance and voicing of the speaker will be severely compromised and offer no advantage over that of the single amplifier method - the close knitting of the drive units and integration will be come disturbed by feeding differing performance of sounds to the differing sections of the loudspeakers, the coherency will no longer be seamless, almost disjointed in delivery.

If in doubt, consider bi-wiring which reduces the distortions generated within the loudspeaker circuit, revealing more detail; otherwise masked by the bass drivers associated back EMF.

So..
I was ok selling off my unused un need MA6500 Integrated Amp to get the amp needed to BiAmp..
But I'm definitely not keen on selling off my MC7270 to start from zero as the Amp is excellent.
So how to enhance performance..another 7270 ??
If I was wealthy Id get a pair of MC2000's and see if I like em better but till then..
