What McIntosh Amp With Thiel 3.6 Speakers?

Mitcheft is correct in his discription of MC-300. I used to own it myself before I upgraded to the MC-352. Although it may look like the amps should be similar, they are totally different in character. The MC-300 is a bit brighter in the upper mids and the treble, sort of glitzy, nice, but not perfect. The mids are nice but are a little higher pitched than the rich mids of the MC-352. MC-352 has beautiful, nicely resolved treble, a little recessed upper mids, rich and refined midrange, great bass with excellent extension and control. Both are wonderful amps, but MC-352 is a much better unit. It walks all over its older brother in transparency, dynamics, bottom end extension and control. At the same time it's lush and musical, never sterile or uninvolving. The bigger MC-602 is very similar and I really don't think it's worth the price difference, and I can't imagine any speakers that would significantly benefit from from such increase in power. The 350 watts of the MC-352 should be more than enough to drive even the toughest loads.

The 352 is a great amp and I agree it is a good choice here and anything above in the Mac line would be slight overkill but certainly if money is no object than the 602 would be nice.

Symphony Sound - Just a note: The Thiel's impedance is not "eratic", it's just low - under 3 ohms through most of the range, about double that in the low bass. The curve is actually quite flat, and the electical phase characteristics are fairly benign. But you are probably right about what to use.

Zaikesman, at the risk of being the victim of your wit for repeated offense, I belive the word eratic was used in the less frequently used sense of deviating from standard. Your point is well made and I'm sure you clarified this too many who otherwise may have been misled.

I own a pair of Thiel CS 2.3's, and drive them with Mac's MA 6900 integrated amp. It has autoformers. I support the above suggestion to use one of the Mac amps that has autoformes with the bigger Thiel's -- In general, I find the Thiel - Mac combo very satisfying.
