Class D amp driving Thiel


I was honing in on a 2 channel system and had seriously narrowed down the contenders until last Saturday. After not being impressed with a pair of B&W CM7's I was encouraged to listen to a set of Thiel 1.6.

It was amazing. Driven by a Bryston amplifier they had detail and precision with beautiful tonality. Yes, they did lack bass under 50 hz. But completely different and world's better than the Thiel's I owned and powered with tubes years ago. So now I have to rethink things. I have only a small shelf for the SB3 and amplifier and can't fit (or afford) anything above 30 lbs or 5 inches tall.

Maybe a second hand Krell 400xi would work but Krell's rap is that they can be bright and fatiguing. And I can't do anything bigger or costlier. While the Naim forum has good reports of Thiel's being driven by even a Nait 5i I am a little cautious based on my previous experience. As I learned the hard way you have to muscle up on Thiel's or they sound bright and nasty.

So, the thought of a class D amp came to mind. Small, light, and powerful. Though I haven't even heard one before (hard to find them in Chicago, believe it or not) my interest is piqued. But would it be up to driving the load I am contemplating without getting bright or harsh? Any thoughts but more importantly experiences are appreciated.

Reps at Thiel suggested to me that at least for the moment, class D amps are fine for subwoofers, but, for the rest of the range, they still have a ways to go to match the alternatives.
Vicdamone, the Thiel reps said it in just such a context, as a gross generalization, that should be taken in that context, with the obvious exceptions that may or may not exist, in other words, so far as they have heard. Mind you I'm very optomistic about this technology. I suspect great things on the horizon, if it hasn't already happend. IMHO, the TacT approach appears to the most promising. I agree with Denjo's suggestion, try it for yourself.
Steve, Unfortunately I can't seem to veryfy it but, I believe the unique TacT class D (perhaps the only true class D) amps (on the other hand perhaps they're not amps at all?) can pass a square wave.
