OTL amps with Wilson Watt/Puppy 6s

The EAR 534 is a great amp - low maintenance and versatile - independent gains per channel and balanced input options and can be bridged for mono - looks great also .

How about Graff?

The Berning amps are not OTL amplifiers.

The EAR amp is not an OTL amplifier!

The Berning amps are OTL amplifers, read the technical data on the David Berning website. They are a highly advanced OTL design, I believe that is why this may confuse you. Just because this design does not correlate with other designs based roughly upon original Futterman principals and/or designs certainly does not mean this is not an OTL amplifer. Read the technical data on the website or e-mail me for more specifics which are clearly laid out within the pages of the instruction manual. This is clearly not anything like the old school of thought on conventional OTL's which for the most part incorperate "brute force" technology. There is nothing wrong with the sound or design of many of the favored OTL companies/products and that is not the point that I am attempting to make. It is my point to illustrate that the current David Berning designs represent a state of the art assault on traditional OTL design drawbacks and represent a giant leap forward in OTL design technology. Who would gripe if every OTL amplifer possessed the ability to mate with much larger varieties of loudspeakers as a result of impedence swing tolerances and at the same time retain the wonderful sonic characteristics of an OTL???
