Thiel Owners

@yyzsantabarbara, I’m a firm believer in working backwards: budget, room, speakers, amplification, etc.. But I offer this with sincerity: perhaps your affection (which might be well deserved) for the Benchmark might lead you to more compatible speakers?

@jon_5912, I think you mean 64 Watts for 102 dB. And one would need 256 Watts for 108dB. Now one would not ordinarily play Thiel’s that loud, but should it happen you wouldn’t have to worry.  Ultimate volume levels are a Thiel weakness. For me the Thiel virtues outweighs the compromises, and the speakers that can play that loud are too compromised elsewhere for me. Though not the last word in accuracy, I’ve used a phone app to track my listening volumes in my roughly >3800’cubed room for a few weeks. The average sound pressure was about 85 dB, but there were peaks a few times each day of well over 100 dB.
It’s not the ultimate power of the Krell’s that impresses me the most, but rather the ease in which it handles low impedance loads. There’s nary a strain, and it’s reflected in the sound. BTW, with my >4 Ohm Thiel’s I use a less powerful amp that’s not a Krell.

Your comment ties in the what John Siau emailed me today.

When ss amps clip, it’s sudden and ugly. With ss amps t’s best to keep far distance from the clipping point.

John’s last comment in the conversation.

Yes, it will work well in your application. The feed-forward error correction keeps the amplifier distortion-free when driving low impedances.

Or maybe distortion and clipping are not the same thing? 

Regarding searching for new speakers. I am very happy with the CS3.7’s I am enjoying the heck out of them now. I am just trying to squeeze every bit of performance, especially in a challenging room. What I have now is great, let me try for excellent which the CS3.7 is capable of. I do want the 2 COAX’s to measure the same though. Need to fix that.

I am going to one day build out a living room system. That will be using different gear and the speakers will likely will be the KEF Blade or Yamaha NS5000. Along with the CS3.7 the other 2 are my fav speakers. A shame these things cost money.

@yyzsantabarbara,@yyzsantabarbara, “A shame these things cost money.”
Haha😄

@jon_5912, Before I forget, let's remember that those calculations were for a 1 meter distance, not the 3 meter recommended distance. Even allowing for the greater efficiency of doubling the channels, and the typical room gain, in practice we can expect much greater power demands in typical use.
