actually gusser, I'm starting to think "clipping" is part of the reason people prefer SE over push pull.
I especially think the 12ax7 DC into a 2a3 does soft clipping extremely well. (particularly with the bandwith limiting of small cap cathode bypass)
I don't agree with your assessment on the power supply, but there is some truth in the fact that the whole cap bundle, power supply, insufficient drive for miller etc all are a form of EQing.

Fine to disagree with my theory of how it sounds.
What is your technical analysis of the LSES power supply?
well... I think:
- due to class A and low current draw
- low mu finals allow for less filtering
- ac filaments means there is a noise floor regardless
- small chokes filter HF well
- ultra clean driver stage
that DFs supply works just fine for a 2a3 or 45. I don't think there is any "dynamics expansion."
I'm also working on my first amp with an l-critical choke input right now, so I'm not hard line. I do believe the supply works and is plenty quiet.
also in fairness, I'm actually running the power supply Jeff has now abandoned. So I'm working with a 2 henry choke.. (along with the flywheel input deal)
on a final note, I'll never cut up factory chokes or power transformer leadouts again either. :)
