Power for Thiel 7.2


Would two (2) Classe Ca 301 in mono mode be enough (600 w at 8 and 1200 at 4) or a single Krell stereo mode at 400 w channel 8 ohm 800 4 ohm.
Which way to go?

While Thiel is politely diplomatic, I don't think it's too hard to read between the lines. If one is using Thiel's top of the line product, I think it fair to say that Thiel's top picks might include: Audio Research, Ayre, Boulder, Classe, Conrad-Johnson, Krell, Mark Levinson, Pass, Theta and VTL. I hope I didn't leave anyone out. Check Thiel's web site under FAQ's.
Oops, scratch Audio Research, though they have used them amongst others to demo their stuff in the past.
Thiel's listening room has the CS 7.2 powerwed by a Krell FPB 700cx.
They were powering the CS 2.4 with a BAT VK600SE.
As it has been stated they do not suggest a certain amp to drive their speakers. They only require quality power.

Getting back to the CS 7.2. I've heard them powered by a pair of Levinson 33H and I was amazed at the sound that was coming from an amp that was rated at 150 wpc @ 8 ohms.
I've heard the CS 7.2 powered by the big Mac daddy's 1201, 1200 wpc @ 8&4 ohms, and was not impressed. So from what I experienced do not rule out an amp because it does not put out 600-750 wpc @8 ohms. Audition them in your system and see what works best for you. A lower powered amp might work if you do not listen at high volumes or have a large room to fill with sound.
Thank you Rtnl for your kind advice.

Have had my X250.5 for months now with fairly intense twigging.

Agree with you entirely. I think the weakest link for a pair of speakers like these is certainly the amps. Do plan to try either the 600.5 or the XA100 maybe in a few months.

Biggest improvement was a harmonic tech fantasy AC to tame the esoteric which perahps mated with the metal diaphragms of the Thiels were a bit bright sounding.

O, forgot, also changed to Synergy IIi in the meantime, and this is a much better mate with the X250.5.

I am reasonably happy right now with this combination. Need another power cord for the Synergy, currently using Zu Cable Mother PC.

Thus far, I must say the musicality from using Maggies previously is almost there (yes... hard to believe isn't it...). The Harmonic Tech pushed the highs, improved transients and squeezed even more air around instruments. I hardly listened to music loud and almost always run the X.5 in pure Class A power. But the well intentioned advice on this forum is much heeded and I guess Thiels do need all the juice you can throw at them. Gryphon Encore & XA100 & X600.5 are all the next affordable price range and will try them out hopefully xmas.

Many thanks again, happy listening
