Best amp for Thiel 3.6 speakers?


I am looking to replace my existing amp, a 250wpc NAD 218 THX, with something that works better with my large Thiel speakers. The 218 has plenty of power to drive these speakers but I would like to upgrade to a better amp.

If there are any other 3.6 owners out there or just someone with an experienced opinion on a good upgrade I would appreciate any feedback you can provide.

Thanks,

I bought a used Krell KSA-150. The speakers they used to to demo the amp was the 3.6. It was outstanding! I was very impressed how well they worked together. When they took the amp out it was replaced by a Aragon 8008BB it was a good match also. I liked the Krell better.
I juice mine with a Classe CA-301. I agree with GS556 on the MIT cables. I started with 750 shotguns and 330 interconnects (balanced). This made for some very good sound. Then I went to 770 twin with 350 ref. twin interconnects and a MIT ref AES/EBU digital cable. This made for great sound. I also agree that Thiels are revealing and must be set in front of some decent gear. Once everything is right they will knock your socks off. Be sure you give them lots and lots of power, you won't be sorry.
I'm driving mine with a McCormack DNA-1 Deluxe Revision A Gold and I have no complaints.
I had good luck with a Bryston 4B and MIT 750 speaker cables. The sound appeared to be a bit bright but was very dependent on the preamp and source. I eventually wound up with a Classe DR6 preamp, Linn turntable, and Goldmund transport and DAC. Good recordings were fabulous but bad recordings were fully exposed and not enjoyable.
Great speakers, I'm driving mine with a classe ca200, cj preamp, kimber wire - kcag, waiting on some kctg and 8tc. classe offers plenty of power, will drive the thiels as loud as i want to go with no congestion or brightness. One of the previous posters is correct Thiels are not bright the electronics behind them usually are, my system is still on the warm side even with silver ic's. Room placement is critical, they sound best when away from all walls. enjoy...
