What is the best OTL out there?

Best sound is subjective, but if you want the best support, the best service, the best upgrade path, the best reputation and history, then purchase Atma-Sphere.

This is the ONE I've been waiting for from Berning, a Class A single ended amplifier with zero feedback, no iron and 60 watts of power! Sure would love some feedback from those that have heard this system. Unfortunately the price puts it out of the realm of all but the well heeled. I wonder how long it takes David to complete a pair of these amplifiers?

Tubegroover-
Yes. No personal experience. But my history with Rick Brown makes me comfortable about conveying his endorsement.

Macrojack are you referring to Berning's recently introduced 60 watt 845 SET ZOTL amp?

I've heard Berning and Tenor in show environments and have been impressed.

I'm using a full Atma-Sphere rig with Silver Edition MA-1 monoblocks and appreciate the accolades bestowed upon the brand! This gear is extraordinarily agile and will reward you with a spectrum of sound due to its ability to realize the characteristics of any 6SN7 in the circuit.

I'd like to try the Novacrons, but need more power for the MegaLine III.

david berning big splash at axponia and newport. Great stuff.

Check out David Berning. Big splash at the recent Newport show.

Agree with Jmcgrogan2, really when you think about it what is the BEST of anything? The limits of the experience of the responders will correlate to some of the responses you'll get but what will that tell you? Then there is the system itself, and the room, and the power feeding the system. The Tenor was "proclamated" at one time as the best of the best by guys who were willing to pay the most and declare what is best. What is most important is that the electrical characteristics of the amp/speaker interface is maximized, the higher and more stable the impedance characteristics of the speaker the more suitable. Graff, Fourier, Counterpoint (SA 4), Atma-sphere, Trancendent, Berning, Joule Electra, Tenor, NYAL, and Futterman are all OTL's I've heard in different systems over the years including my own.

Not all of the above were known for their reliability but I won't name names. Each are capable of good to great sound in the proper system and room.

If your wattage needs are modest, less than 20wpc, the new Music Reference OTL is absolutely amazing. Heard it a week ago on loan from Vaughn Loudpeakers. Get the one upgraded witb Eichman posts. Must be heard to be believed....
The Atma are no-brainer choices. They have the design very refined.

The Joule Electra Right of Passage is a pretty special amp (probably the Destiny as well, but I have not heard it). That leaves room for 8 more

Yup, so 2 of the 11 are Atma-Sphere and Tenor. That leaves room for 9 other votes. Cheers,

how many OTL manufacturers are there currently in production?

I've listened to a few different ones and have to say the Atmasphere Novaron's have been my favorite. Now with that being said you must, with any OTL, use a speaker that has a flat impedance and the higher the better.

Try Atma-Sphere. I would be surprised if you were disappointed.
