Intregrated Amp for Thiel 2.4 s

I have also found the GamuT D200 Mk III to be a great amp. As a 20-year tube system person, the Gamut D200 is the only SS amp I have tried over the years that maintains a similar sense of harmonic completeness with no typical SS down sides. (Tried BAT VK-500, Plinius SA102, Goldmund M28, 47 Labs Gaincard-S, Sunfire stereo amp.)

Tonal balance is neutral with no glare, no listener fatigue, good dynamics, good bass extension and punch, etc. (Speaker = Coincident Super Eclipse III.) I would not be surprized if the D200 mated well with the Thiel 2.4, but give it a try first, of course.

I use a Gamut D200 Mk2, and it drove my Thiel 2.3'svery nicely before I got my current speakers, the Vr4jr's.
Iagree with Kalan, a very smooth amp with low fatigue factor. Seem to be available used a fair bit, too....on Agon

I once hear a pair of Thiel 2.4 driven by Audio Research tube preamp, Audio research SS amp using Acoustic Zen cables and the whole combo sounded fantastic. Probably one of the best soundstage I've ever heard. Can't recall the model's name though.

Try the McIntosh MA6900. I think the list price is now near $5,000, but there are usually a couple of used ones available on Audiogon. McIntosh amplifiers lean toward a warm full sound, which to my ears works very well with Thiel speakers.

I agree the MA6900 would be an excellent match for your speakers. The A5 would be good too IMO.
