OTL amplifiers

I currently have a pair of Tenors. My last amps
were Bat 150se's. Both amps are very good, but
there is a thing that the OTL does that makes
you smile every time you listen to them. I'm using
Verity Parsifal Encore speakers(4 ohm) and the
Tenors do just fine in a medium sized room. They
do run out of steam at loud volume, but at that
level I'm sure there is some ear damage happening
anyway. You just have to hear OTL's matched to the right speakers.

Fuzzy feeling....I loved that. You are a lucky man, Wellfed. Hope you have it again and again and off the same sources!
Clueless, yes, those were wild and reckless days, there was hype of course, as always, but it was less brash, less cynical and Fulton was the only one with cables and a little later Mark Levinson, the man, before ML became Madrigal, his by the way were made in Switzerland. Futterman died much too early. Harvey did the repairing but mine never made it, because he was again in one of his bankruptcies. ( Did not have enough grannies, obviously )
Cheers,

Detlof, I'm going all nostalgic! I still have a pair of Mark Lev IC's.

Great stuff...
Futtermans driving Quad 63's (no protection circuit, of course), blowing up on me on a Saturday AFTERNOON...
There was lots of suspense then with the F's: are they biased? (never), will they play? (that's the exciting part).

Back to the question. Can't give tech & other details well covered above.
So, subjectively, OTL's offer an immediacy in the sound and, often, musicality -- I don't mean "tube warmth" (even order, benign distortion). Good microdynamics, giving these amps the "fast" label.

On the other hand, they're picky about the load they can drive, they're expensive and, until recently, not very reliable.

Interestingly enough Detlof, Harvey's "wretchedly excessive" Futterman's are still being used by someone I know to good effect (last time I spoke with him) with nary a problem on a pair of Magenapan Tympani 4"s. I suppose he is one of the lucky ones or maybe this particular *Child* of Harvey has an intrinsically sweeter personality or received more attention during the formative years?

Tubegroover, Harvey DID have his inspired moments, which this "child" must have sprung out of. I alas, was not that lucky. By the way, I would imagine that this combination, you've mentioned, must sound absolutely heavenly.....
