Amp for Thiel CS6


I currently am using a Conrad Johnson MF2500A to amplify my Thiel CS6 speakers. At times it seems as if the amp does not give as full, or solid a bass response as I would like. Is this a potential issue with the MF2500A? I am considering either a CJ Premier 350, or a Rogue Audio Zeuss. Any thoughts about these, or other amps with the Thiel CS6 speakers? Thanks.

Droz, I just found this thread - the advice from Thiel owners is spot on. I drive 3.6's with Mcintosh 501 mono's. My final choice was between the Mac's and CJ 350 which btw, is a superb amp. I felt the Mac's were better, more control in the bass for sure and more tonally accurate and pleasing through the midrange. Both have great top end extension. I wanted the CJ to work since I have been using CJ preamps for many years.

I can tell you the difference between my former amp, Classe CA 200 and the Mcintosh mono's is night and day. Thiels are just a different speaker when driven with adequate solid state power.
Thanks for all of the input. I have now decided to go with a solid state amp, rather than the Zeus. Given my present preamp, room set up, cabinetry, etc. I think I will try to find a Conrad Johnson Premier 350 to upgrade my system. Thanks again to everyone for your valuable insights.
One huge vote for Rogue. Have you heard the Zeus? It's amazing. Fast, fast pace and detail.
It has been recommended that I consider the Mccormack DNA 750 monoblocks as another possible choice with my Thiel CS6s. Does anyone have any experience with this amp with Thiel, or other speakers?
Thanks.
I like McCormack amps a lot, but they're not my favorite choice with Thiels. I think the McCormack amps are a bit forward for Thiels. The best amps I've heard with Thiels are real Krells.
