Does Mcintosh MC75 drive B&W 802D well?

If the speaker posses a relatively flat impedence curve and doesn't drop below 4 ohms then you should be fine. Of course it still depends on room size, type of music and how loud you play it.

I don't think it proves enough juice. The tonal propeties are probably fine...rolled off highs, but those speakers need more power

I agree: not enough power. I own MC275 with B&W 804S, a much smaller speaker, and the combination is very good. I know of people using MC275 as mono amps to drive 802D and claim to have very good results, but 75W I guess wouldn't be enough.

Unless of course you look at it as an intermediate step until you get a larger amp.
Can you audition the combination?

You can always try it and if it is not enough upgrade the amps. This of course assumes you like the sonic character of the B&W's and wish to build a system around them.

I used a cj premier 11a (70 wpc) amp to drive a pair of Thiel 3.6's and it did a very good job. The Thiels are known to be a very demanding load with an impedence curve droping into the 2 range and a sensitivity of around 86db.
