so a gapped push pull might help, this gets Shaib off the hook,
Great post, CJ, much of the details flying above my altitude...CJ said:but some people like the SE sound, which features more odd harmonics than push-pull
this is because the p-p circuit tends to cancel odd harmonics.
this is also why SE amps tend to sound crappy at first,
we are so used to p-p circuits as they are more efficient and cheaper,
99 percent of all the amps you listen to in your life will be push-pull.
but once you get used to SE, the push pull will lack some character.

But I'm still learning.. ...
Sorry for reviving an old thread but I am trying to go back and read as much as I can about this stuff.What you say is true. However, you do not have to use a gapped transformer in a single ended design - the alternative is to capacitively couple the transformer to the single ended stage in which case the transformer does not need a gap. In general terms, this means the transformer will have better performance than its gapped equivalent. The RED47 does this for instance
