OTL amps

Like Vtvu, I have the 25wt stereo Transcendent Sound OTL and for $1,900.00, it is extremely good. The sound is very transparent and lets you hear everything going on in the recording, which can be good or bad. Because of it's incredible "clearness" it seems to somewhat mask the delicious juicyness that SETs give you. However! I'm now driving the woofer of my Proac Response 2.5s with the Transcendent Sound amp and the tweeters with a pair of Cary 2a3 monoblocks. This set up shows the wonderful midrange clarity and body that OTLs are capable of since the 2.5s cross over somewhere above 2500HZ.

Check out the David Berning products. Just a note, the Berning ZH-270 increases power as ohm load increases, unlike other OTL's, in which it is just the opposite. Really, it has the most advanced designed layout of any OTL. Check out the Berning website for more info. This little, non obtrusive amp had the most power and drive I have ever heard period. The bass had to heard to be believed. Advanced technology and design layout are extremely fascinating, but the sound is where this amp shines. Incredible. Note : To the man that posted above about purchase of the Berning - Hurry there are only a few new units left. David Berning does not build many period. If I had the extra money I would sell my beloved little Blue Circle BC22 (solid state) and scoup one up. BTW the ZH-270 has an estimated 20 year tube life. Amazing.

thanks for your response about the ZH270, however the more i read about OTL's i m discovering that you really should be using an elecro-static type speaker vs a conventional dynamic one, any thoughts about this?

We are currently using Harbeth Compact HL7ES's and Jean-Marie Reynaud Twinn MKll's with the ZH-270. The David Berning ZH-270 works extremely well with dynamic speakers such as these and I am confident that it would also mate well with various other dynamic speakers with modest power requirments. There has been no indication that the David Berning OTL is limited in any way for exclusive use with an electrostat speaker. Our dynamic speakers match perfectly with this OTL in every aspect. This amp must simply be heard to appreciate. It has impressed me more than any single piece of gear I have heard, period.

Thorty40, Have you heard any other otl's?
