Speaker for McIntosh setup

Newt

james633,
I agree with you. Many speakers will work well and sound great, but stay away from dark sounding speakers. I would never team it with B&W, but then I don't like their speakers.

Focal Electra 1038 BE
Focal and McIntosh pair very well

So I have heard a lot of good review of the new Klipsch Heritage line.  Would the Heresy IV or the Forte IV work well with these older McIntosh units?

I can’t answer you question directly but I can give some klipsch Mac input. 
I use Klipsch RP8000F in my home theater but when I broke them in I hooked them up to my two channel rig which has a MC462. The MC462 and the RP8000F really made me question a lot of things. It sounded plain out good. The mids of the klipsch lack the presents and last bit of detail (but not bad) but the highs were great. The bass was deep but also lacked the last bit of detail. All in all way better than a $1000 speaker should sound in my mind. 
I was a bit dumb founded as how such a cheap speaker with a box that was super hollow sounded... well good. Interesting for sure. But who would hook up a $1000 speaker to $15,000 worth of electronics. 
I also demoed the Cornwall IV on a McIntosh 7200 integrated. It sounded so so to me with kind of odd bass that did not seem to blend well with the mids. It could have been the room etc. I need to give them another try at a different dealer/room. I have two in town. The highs were very nice on the Cornwall iv Mac setup though.
