After listening to a fair group of SE amps, I have yet to hear one I wanted to build, except for geetar amps.
For stuff SE needs, like gapped OPT's there is some benefit to the linearizing effect this has on the sonics delivery. I may try gapped PP at some point if I can live with the reduction in LF performance the drop in overall primary L gives. Since I run electronic cross overs, this could be sooner than later...

Bi-amping is your friend: I run parallel single ended 2A3s above 160Hz and McIntosh push-pull tubes in the bass.
"Bi-amping is your friend"
I totally agree.
Gapped transformers and good bass performance are, IMO, mutually exclusive.
The gap reduces the inductance, the reduced inductance causes the loadline to become elliptical (in the presents of low bass) and all the frequencies follow that elliptical loadline increasing the HD.

Yah, it is a fight...for the bass amps, I think I want as much as I can get. Anything else above that, the gapped core sonics are not to be despised.
It does not take anything like a SE, full Class A idle current worth of a gap to be of use. Just enough gap to knock 10% off is quite worthwhile. it is likely one of the reasons I like cut C-cores; their effective gap is much larger than an interleaved stack of E's and I's.
I think I need some 49% Ni cut C's...
