Thiel Owners

Hi Tom - I own Thiel 3.6 and have for around 17 years and CS 6 for about 4 years.  I switch them in and out every few months or so, right now using the CS 6.

The only amplification I have used are Mcintosh 501 mono’s and Classe CA200, both of which I am intimately familiar with since I have owned both for several years.

Both are interesting, the 501’s have an obvious control over both speakers.  The Classe’s also have plenty of control, great midrange textures and are more open than the darker sounding Mac’s.  The Mac's might have a small degree of refinement compared to the Classe, perhaps the addition current.  Neither amp ever gives the impression of being “taxed” no matter how hard they are driven.  And I have been know to drive them with some good classic rock, blues, and jazz.

My room is large, 18 X 40 and I get plenty of Satisfying SPL  with both amps.  I also switch them in and out every so often.

Pops - What is the power rating of the Macs? Do you use the 4 ohm tap?

The CA200 is rated at 200 into 8 ohms and 500 into 2 ohms, so it is current limited, which interests me. Have you used it in both stereo and bridged mono? 

What is your ceiling height on that great room?

Tom - the Macs are rated at 500 watts from each tap, I have tried all 3 and prefer the 4 ohm tap, interestingly, the 8 ohm tap sounds good too. Bass is a little smoother. The 2 ohm tap does have a little more texture in the midrange - I need to try it again.

I have not bridged the Classe as I only have one. Have always been interested to try it however and flirted many times with buying another one.

The ceiling is the most interesting part of my room. I used Rives Audio to build out my basement, hence the 18 X 42 foot size. We used the floor joists to build a giant diffuser by using blocking between joist bays, blocked at 15 to 40 degree angles in each bay. Over 380 blocks - I think my contractor wanted to hang it up when he read those plans! Then we treated and covered with cloth so the ceiling actually plays higher than 8 ft. There are 3 soffit areas, the first 2 are a combination of diffuser/absorption where the music takes place. The last soffit is geared more for absorption to deaden that end of the room.

I have a pool table back there. Great to lay stuff on and collect dust rather than actually play pool! LOL. The room really does sound great and was the best investment I have made in my system.

Room sounds really nice. That smallest floor to ceiling dimension is a significant limiting factor to normal playback rooms. Good work with your ceiling treatment.

I'll post when I have some feedback regarding bridged mono vs vertical bi-amping performance.

popsYour room does sounds nice indeed.  For most basement designs this is not an easy task to conquer.  Agreed, good work with your ceiling reinforcement, treatment.  Happy Listening!
