Tom Thiel and Harrylavo:
Hello Tom, this is my first post in this forum. I have been posting only in the SteveHoffman.tv forums for the past few years. Today, I just found out that you are here. So, here I am too.
During the decades of owning my Thiel CS3.5 speakers, I have tried hundreds of amplifiers with them, and can remember my sonic result with just about all of them. Adcom NEVER sounded good with Thiels, no matter how much power. Together they sound bland, lacking in dynamics, and electronic (not natural). The Amber Series-70 was an excellent combination in every way, one of the best I ever heard. It had actually only about 60 wpc (but it was famous for a having a VERY large power transformer and capability to deliver high current to low impedance or wildly varying impedance speakers). The other excellent matches were Classe DR series amps, all Mark Levinsons, and all Krells. But when I started hearing tube amps with Thiels, I never went back to solid state with them. Even very low power tube amps sound REALLY great with Thiel CS3.5. In fact, I never found one tube amp that didn’t sound great with them. Even a 6 wpc SET amp from AES was awesome. Now I am using Audio Research Classic 120 mono amps with my CS3.7, and it is an impressive match with the CS3.5 also. I think $3000 for a pair of these amps is a bargain. With my 3.5s, I am still using my MFA (Moore Franklyn) M-120 amps in triode mode, 60 wpc. When listeners hear this system, they cannot believe that I have been listening to such great sound for about 30 years. Newer, comparable amps would be from Bruce Moore Design, but are expensive. So my advice is that just about any stereo tube amp, with at least 60 wpc, into the CS3.5 is pure heaven. With solid state, you need to be more careful to audition in advance, and don’t go lower than 100 wpc in power.
