I like the ones which call out "single ended" and "class A" as separate virtues, as in, "not only is it single-ended, it is *also* class A". And that too, in a linestage. How many push-pull class B linestages are there? PP maybe (or more likely, balanced or differential, neither of which would be single ended, right?), but I really wonder if there are many non-class A linestages.
As linestages go most are run in Class A and SE.
If you think SRPP or White CFs are PP then that's not really PP to my mind.

Now if you want something really outside common thinking I'd use an OTL linestage running in balanced operation with a balanced constant impedance volumecontrol preceding it.

That would use a true bi-polar tube regulated supply as well...

Add a tubed Widlar current mirror to clamp the cathodes and you'd have a hell of a linestage.

And, no, I didn't patent the idea...yet.
