Best affordable amp for Thiel CS3.6


I have a pair of CS3.6's, which I am currently driving with a pair of Adcom GFA-555II's in bridged mono mode. While I am fairly happy with this setup, I realize that the Adcoms may not be in the same league as the Thiels. Any suggestions as to what amps mate well with the CS3.6's? Ideally, I'd love to find an amp (or two, if mono) for under $2,000, but if it's worthwhile, I may go higher. Obviously, if there is a great option out there for less money, I'd be even more interested. Used gear is fine with me, if it is quality gear. I am also considering modding my Adcoms to smooth out the mids/highs and add a little support in the low end.

Another consideration is that I am currently using an Adcom GFA-2535 for my center channel (Thiel SCS3) and surrounds (AR TSW-110), and since it is nice to have matching amps for HT, I'd probably have to add an additional amp or two (eventually).

My sources are currently a Denon DCM-460 and a JVC SA-600, but these are likely to be upgraded in the relatively near future. Both are sending digital outs to my Rotel RSP-1066, which handles the processing.

Thanks for any input/advice.

Tom.

Tom, I haven't actualy heard them, but, considering the pedigrees and history with Thiel, you migh want to consider Threshold and Coda.
OK Tom, bear in mind that a lot of this is subject a lot of personal biases. I love the Krell on Thiels. IMHO they are not nearly as bright and lean as some make them out to be. While the McCormacks have nice tight bass and smooth liquid highs, I think they can be some what forward and shouty, not something that would compliment the Thiels. I haven't heard the Theta's. The Brystons are nice, I particularly like the 3BST. The Brystons are probably some where between what you have now and the better amps on your list. How ever there has been some talk here on Audiogon with regard to their inability to handle low impedance loads. Considering your 3.6's drop to 2.5 Ohms, I'd be more than a little cautious. I find the Classe' a bit soft in the bass and a bit chalky on top. These critisims should not be taken out of context, I really do mean a bit. Rumor has it that the 200 Watt and above models are superior to the lower powered versions. The Classe' is probably between the Bryston and the next level, but I wouldn't argue if others placed them differently. The Classe' is a sound choice for the Thiels. The Pass X series might be the best amps I've ever heard. I love the lack of electronic flavor/haze that dwells in so much solid state gear and they are a lot cleaner and more dynamic than the Aleph predecesors. They should work beautifully with the Thiels. Unfortunatley your budget may prohibit the power levels your accustomed to. From your short list I would consider in order: Pass, Krell and Classe'. If any others come up for consideration I'd be happy to share my arrogant, pompous point of view. While I think that amps may be more important with Thiels than most speakers, try not to forget how the amps will work in the complete system, now and in the future. Good luck
Tom, you are very intuitive. That was exactly my point. Mind you there are some very good deals on the used market. Your current budget may force compromises. For just a little bit more money you can get the level of finess that will be a forward rather than a lateral move and the amount of power needed to really to push the Thiels. The cash outlay isn't really that much more on the used market.

The longer the amps run in class A the more heat it is likely to generate. Mind you many believe that this extended level of class A is exactly what makes them sound better in the first place. Depending on the model, I suspect the Krell and Pass will run the hottest and IMHO will sound the best.
P.S. not all Pass amps are candidates for speakers that drop to 2.5 Ohms. Some of the older 2 stage Alephs don't take kindly to to that kind of load. There are others that just might sing though!
I think we have to be cautious about lumping components with similar technologies into overyly broad generalizations. Some typical ss amps do well with lower impedance loads, some rare tube ones can work well too and visa versa. I suspect different digital amps may follow suit. I'm very excited about the potential of these new digital amps, but, have very very little experience with them. I've only heard them at shows. One product in multiple situations which didn't impress me too much and another in one situation that really did impress me.
I'll pipe in with some more arrogant, biased opinions. The Rowlands are similar to the Levinson gear. They both have a some what soft laid back presentation. A little too laid back for me with the Thiels. The Thiels while adequate are not the most dynamic speakers, (this may seem contradictory) yet with the wrong gear they can be a bit up front. Where I think the Rowlands surpass the Levinson stuff is in the rich, lush soundstage and harmonics that belies it's solid state technology. Not my personal first choice, but, I can ceratinly imagine it being someone elses. I might pick the Rowlands as my third choice. If you can find one at the right price it could be a worthwhile consideration. I don't think the intergrateds can handle the load, it might be safer to stick with the seperates. BTW, Rowland has great web site, with details about past products readibly avavilable.
