Anybody using tube amps to drive Thiel CS 3.7's ?
I currently use a Classe Delta 2200 and a Conrad-Johnson CT5 preamp. I'm considering a jump to a tube amp. 80-100 kohm input impedance would be nice and I'd prefer only input from those who've heard Thiels driven with tubes...Thiels are hungry for High quality power. I have a moderate sized room (21 wide by 15 long). Let me hear your advice.

I recently purchased CS3.6 and play quite nicely with my ASL Hurricane monoblocks. They put out 200w/ch in pentode mode. I'm able to achieve pretty high volume levels with no clipping and my room is about 17' x 19'. Sound treatment and placement are key and I find the Thiels are very sensitive to toe in and side wall reflections. You might want to consider the ASLs which are pretty highly regarded and provide a very good # tube watts/buck. Good luck! |
Vhiner I have been using VAC PA90E1 amps with my Thiel CS1.5 speakers for about 4 years with no problems in triode (50 watts) or ultralinear mode (100 watts). Kevin Hayes @ Vac is very familiar with Thiel speakers and uses them in his own house. He can let you know which of his amps would work best with the CS3.7's. I would give him a call. |
These Thiel’s need an amp with grunt to sound their best, lots of current, that really means Tubes or Mosfets are not ideal. Amps that can almost double their wattage from 8ohm to 4ohm to 2ohms, would do the right thing by them. From the Stereophile test results. " I actually found the minimum impedance to be 2.4 ohms at 125Hz. The difference between 2.8 and 2.4 ohms is academic, either mandating use of an amplifier that has no problem delivering high currents" http://www.stereophile.com/content/thiel-cs37-loudspeaker-measurements#POtrL7hdCUOxjofF.97 Cheers George |
