Reaplce Thiel 3.6's Tweeter

Messing with the tweeters in kinda like messing with an older Chrysler Hemi engine...DON'T DO IT!!! Even if you do tune the system to your ears, you'll destroy the resale value of your speakers. Work with other components and assorted tweaks further down the audio chain.

For classical music, I would recommend vinyl, SACD, or DVD-A for a source. CD's just won't cut it on violins and violas...redbook CD's will give you a slightly etched, grainy, or scratchy presentation on these instruments. Very subtle on the best CD players, but still there

I am not familiar with counterpoint electronics but I have Thiel 3.6's with all conrad johnson electronics and they sound wonderful. I listen primarily to classical and female jazz vocals.

As a Thiel owner, I absolutely agree with Pops: your first move should be to try copper cables and to take the Chang unit out of your system.

I'm not familiar with your Counterpoints but it sounds like you are bridgeing a 2 channel amp for each side. I tried this my 3.6's and did not like the sound. Nor did the amps like the heat generated. I believe an amp in bridged mode sees half the impedance. This combined with a 2.8 ohm min. is bad news.
