Thiel Owners

I forgot to add the Math;i = 66r = 4
v = ir = 264
w = 264x66 = 17,424
1Hp = 746 watts

66 (A)mps into 4 Ohms = is 23.35 Hp.

Pardon me Jay, I neglected to mention that phase characteristics in the speaker also influence amp performance. Phase lead and lag illustrate reactive characteristics of the load, which are far more difficult for an amp to drive than a purely resistive load. Thiel speakers do a good job of presenting a non-reactive resistive load which allows the amp its best shot of capably driving that load. So, even though Thiel impedance is very low, requiring lots of current, at least the load is fairly benign.

Thank You for your continued contributions to this thread and the larger cause at hand.  How are you enjoying your re-vamped Classe' amps?
Happy Listening!

Jay - the Classe amps tell a long story. The tech is in some kind of trouble and still has some of my gear. Classe had recapped one DR9 a year ago. The new guy replaced and bypassed some signal path caps to match our plan for the second DR9. We also recapped and bypassed the DR6 preamp, so the "new" sound results from the combination.

It sounds very good - the "dark" sound of the DR9 seems to have lifted - more incisive and articulate which is what I need for both recording and XO hotrod evaluations. The second DR9 is still in the shop for its total recapping / bypassing. April 11th: " a few days to get parts and a week to do the job." Very long week. Not yet, maybe soon.

Oh my, looks like trouble indeed. Hope this tech becomes a "stand-up" Guy and finishes the job as previously arranged. If not, feel free to post as much information as you wish to warn the other Classe' owners out there.Keep us posted.
