In Reply to: I didn't say OTL's sound bad posted by Atexanathome on July 17, 2006 at 19:55:10:
HI.Julius Flutterman's original 1954 OTL design indeed used tons of NFB to balance it. But the O/P impedance was still pretty high.
With an improved "A variation on the Flutterman" OTL topology, the O/P impedance drop up to 4 times, e.g. 6R something. NFB still needed, much less scale.
With differential balanced bridge amp topology basing on the 1951
original Circletron achieves really balanced O/P without need of global NFB.How good does a really good OTL amp sounds? I can use a few words to describe one: smooth, silky & deep 3D.
