Thiel Owners

@xyzsantabarbara, As I understand it; yes. I believe many of the Krell’s do, that the Mark Levinson ML 2’s did, some of the Pass Labs might (limited to 4 Ohms maybe?)? I wouldn’t swear on it though. I’ll hazard a guess that the Class A output is halved as the output doubles as impedance is halved. Though most times one cruises along at low power output, that output increases rather dramatically exponentially. You’ll have to decide how relevant the Class A output in your circumstances. Keep in mind that available higher total output can potentially protect drivers from under powered clipping damage, and the ear tends to be less sensitive to the cross-over distortions of Class AB at higher volume levels.
These are the areas that separates typically have advantages over their integrated brethren; the ability to double down and and the ability to stay in Class A output longer when doing so.

Did anyone hear EAR Yoshino pre-power with Thiel speakers ?This brand is very musical but i wonder if EAR monoblocks could handle Thiel load.

One of my CJ amps had to go in to the shop momentarily and an audio-pal lent me his Bryston 4B3:

I tested it on my Spendor S3/5s and then my Joseph Audio Perspective speakers.   I had the usual reaction when I use solid state:  wow, neato grip and power, density, transient edge vividness etc.  Really fun.   But once I got my CJ amp back and compared...I was definitely still in the "tube" camp.   They sounded about as powerful, but richer, fuller, more organic and beautiful.

Next up I'll be trying the Bryston with my Thiel 2.7s.   I've never heard the 2.7s with solid state so this should be interesting. 

^The Bryston 4B3 is not spec’d into 2 Ohms, and isn’t spec’d to double down from 8 Ohms into 4 Ohms. I wouldn’t consider this amp as a testament of the full potential prowess of ss amplification with the Thiel 2.7’s.

As a point of Thiel history, Jim used very good amps to design the speakers. His attitude was that making a good amp was the ampmakers’ business, and making a good speaker was his business. We generally had on hand the best from Levinson, Krell, Audio Research and others for comparison. His workhorse for the 3.7 development was the Krell FPB-600.

But at shows, Thiel usually exhibited with amps priced commensurate with its products. No $30K amp for a $10K speaker. Bryston was often used. I found the Bryston amps rather coarse compared to the better stuff at the factory. Many reports said that all changed with Bryston’s ’cubed’ series - which are more refined. Thiel used the a cubed series amp (perhaps 4B3?) to introduce and show the 3.7. That was the combination that George Cardas dubbed the best sound he had ever heard at a show. Bryston offers trade in and upgrade packages. I suggest that the ’cubed’ Brystons come very close to supporting Jim’s design intent for the 3.7, even though it doesn't meet the double-down standards for full current delivery into low impedance loads.
