Thiel CS3.6

In fact there are quite a few Mark Levinson 23s (referred to in the review) on Agon right now for sale in the $1700-$2200 range. Good luck

I totally disagree with many of the above, VAC voiced their 30/30 300b tube amp using 3.6. This amp has 32 watts but they are class A and make the Thiel sing. The only question is how big is your room.

Jab, Thiel seems to disagree with you:

Unsound and Cmalak, I do not see in the manual where they say a VAC 30/30 class A amp will not work. I guess the VAC design studio was wrong. The Thiel manual says that that you should use a 100 watt amp. Is that 100 class A or class a/b? Are they they the same, I think not, my 30 watt class A amp as you infer will not work but my VAC 100 watt class a/b will? Both VAC amps can drive the same speakers, although I believe the 30 watt class A amp has more drive than the well reviewed 100 watt a/b amp.
On a side note I remember reading an article(Audio, Absolute Sound or Stereophile)years ago, that a high percentage of Thiel customers used Adcom 545 and 555 amps. Ouch that must of hurt ones ears, metal and solid state.
