Have thiel 3.6's. Will mcintosh ma6600 work?

The Mac's with their autoformers won't double down into the 3.6's rather challenging load. Not what I would recommend.

I use to have the 3.6's great speaker but hard to drive. They can be in your face a little through the mids and highs, and they need a amp with good tight controled bass.

They do remain mostly under 3ohms, so an amp with good current is a must. Stereophile test measurements here

My self I would look at amps that have reputation for good bass control, but ones with high class A bias to keep the mids and highs sweet. So the hot running medium to large size Krell's, Mark Levinson's and other manufacturers like them would be my choice for these speakers.

Read the full review here, if the 225watt VTL's couldn't do it in the bass, then I doubt the Mac's with transformer output will either.

Hello. A bit off of the subject here but I have CS3.5's which, almost typically, have midrange driver issues. I purchased a pair of suitable Scanspeaks but...they're not quite up to snuff. Thiel no longer rebuilds them and interweb searches have proven futile. I am looking to buy the mids used from a member if anyone knows of a source. I ain't giving up on these yet. Thiei used to charge $300 for the rebuild and that doesn't totally put me off - I bought them used so that's a relatively small additional investment on truly remarkable speakers. Thanks for reading.

^That's really disappointing to hear. Thiel's once legendary customer service seems to have faded away with the previous/original owners. Things are really changing at Thiel, and it seems as though it's for the worse.
Check e-bay, from time to time there will be part out sales of various Thiels. Another option is to contact Miller Sound in Philadelphia. I just had a friend have a Thiel CS 2 driver rebuilt by Bill LeGall there, and he was very satisfied with everything.

Thank you for the tip! I'll be contacting him soon enough. I have seen a couple of possibilities on EBay but the sellers weren't, IMHO, too trustworthy. I sent one seller a photo of my Thiel midranges to confirm that his were in fact original and he could not or would not offer an answer as to why the stickers on his did not have Thiel printed on them. Caveat emptor! Thanks again.
