Reaplce Thiel 3.6's Tweeter

Wow...that's ambitious, Unsound makes a very valid point...

Every component and cable is a little on the sharp side for a neutral/unforgiving speaker like thiel. First thing I would try - go to copper cables, I'm assuming yours are silver. Next, I would plug the amps directly into the wall and out of the chang pc. You will tame the tweeter some and get some body in the presentation.

This seems to me the most inexpensive way to possibly improve the sound and decide if you want to stick with Thiel. You almost need to build a system around Thiels - they will either punish you are greatly reward you.

I've always had a tube preamp in the chain and recommend that with Thiels. Next is a SS amp with alot of clean power like Mcintosh, Classe, or CJ...those are the only amps I have alot of experience with but they all work exceptionally well with thiel.

My final suggestion...don't give up on your Thiels.

Well I can only tell you what works for me so you'll have to take it with a grain of salt. I am an MIT guy, have used many models, currently using 350 reference between dac and preamp, and 350 shotgun evo between pre and amp, using magnum 2 speaker wire.

The only other brand I have extensive experience with in my system is Kimber, PBJ, KCAG, select 1011 and 1021, 8TC, and monocle xl. The MIT's offer, according to my ears, tonal accuracy and a presence and immediacy I have rarely heard even in showrooms with various brands. The also image very good. That said, one of the strong suits of Kimber is the imaging which is phenomenal but the immediacy and presence is not there.

I have Thiel 3.6's and they offer the soundstage you like when properly setup, they need space between them and all walls. I'm not familiar with counterpoint really, I use CJ premier 14 pre and Mcintosh 501's which offer a full lush midrange, huge bass, and very smooth top end. I also use an older meridian digital setup, so all of the components upstream are a little on the "laid back" side. Hope this helps.
