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.

Before the upgrade to the Thiel CS2.4, I was happily driving the 1.6s with my Channel Islands D*200 Monos (class D). The D*200s controlled the Thiels very well and had more than enough headroom to drive my 2.4s!

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.
I would urge you to try any of the class D amplifiers for yuourself - Spectron, Channel Islands, Bel Canto ... to name a few, and to let your ears be your judge! I have tried SS amplifiers from several well known manufacturers but they did not drive the Thiels like my D*200 Monos did!

In regards to the Reps at Thiel. I find it questionable at best, of anybody who would make such a gross generalization. I seriously doubt that anybody has had the opportunity to seriously setup and audition ALL the class D amplifiers on the market today to make such a comment.

Unfortunately there are a few manufactures of class D amplifiers that have discovered the economy and availability of off the shelf components which has allowed them to produce products with less than desirable sonics and large profit margins. On the other hand there are class D amplifiers that are so uniquely designed that their abilities have been very well received. Whether these amplifiers have a desirable synergy with any or all of Thiel products is another issue.

Regardless of the Reps obvious shortcomings I still find Thiel and the importance they place on time and phase puts them in very select company in the dynamic loudspeaker industry.
I'm using Rowland 201's to drive my 3.6's, and I'm very happy with the combination.
