What is the best OTL out there?

I have had the ZOTL 40 for about 3 days and it is killer. I heard it at the Newport show and went ahead and pulled the trigger finally. This is David Bernings most recent design but is built by a small company called Linear Tube Audio. Mark Schneider has assembled a fine team of engineers and is capable of producing these a bit faster than David by himself has been able to in the past. Another plus is the very reasonable price for this new line.

i am enjoying the best my room has ever sounded and it's much better than what I heard at Newport not that it sounded bad. My Janszen zA2.1's have never sounded so good and more than enough power. If you are familiar with David Bernings amps, I also own his ZH230 which was the best sounding amp ive ever heard until I got this ZOTL 40.

I hope someone worked on the Futterman circuit to cure it’s well-known problems. Harvey Rosenberg and George Kaye tried for years without being entirely successful. Both Ralph Karsten (Atma-Sphere) and Roger Modjeski (Music Reference) have designed and offer better OTL amps than any Futterman.

There's some out there who designed and build their own  OTL that uses better tubes like KT88/120/150,,300b,,VV52b,,even 211 / VT 4C can  be used and  they are more efficient than the ones  on the market today.

This statement is false- there are no OTLs based on any of the tubes listed above.

How can you be sure,I build and designed these types of OTL and they sound excellent.using KT120,KT88,VVT52b,300bMaybe you are just concentrated on your OTL.
