OTL or SET? Differences?

FWIW, one thing that OTLs and SETs have in common is that neither has any hysteresis loss in the output transformer.

SETs do not reverse the magnetic field in the transformer, and OTLs don't by definition.

Removing the transformer also removes the argument against push-pull. You don't have hysteresis loss, so you don't get the attendant loss of detail that is an effect hysteresis loss. This means that push pull need not be a 'sin' as mentioned above.

Of course our stuff is all-triode too.

Hysteresis loss is the property of magnetic devices wherein it takes a little bit of energy to reverse the magnetic field in the device. In the case of output transformers, this energy comes from the signal and is responsible for a loss of low level detail and an attendant increase in low signal distortion.

Duke, sorry to hear you are having worries. So far in the years I've been on this forum, no-one has challenged me in the way you mention. For that matter I've not had any posts that could not be approved (that I remember anyway...), but I try to be really careful not to cross the line. Too much:)

Excellent post Rushton, I completely agree with your comments, especially with reference to full range music and the typical listening impressions when listening through OTL vs SET, its true, its true.

Tubegroover, thanks.

Audiokinesis/Duke, you're consistently one of the most balanced and helpful people posting on Audiogon. I'm amazed someone has made a point of attacking you; that's unconscionable. Thanks for all that you've added here over the years, and I hope the nonsense doesn't put you off.

Ralph, I've never heard that hysterisis loss explanaton before. Thank you.

Of course those of us who have been paying attention are well aware of his tt/arm/cart/preamp/amp/spekers. Time to post pictures?
