I presume the Krells are single-ended which is why they are large.


Class A is something else than Single Ended.
Though a SE amp is always biased in class A, it certainly is possible
to make a push pull (or complementary) amplifier that is biased in A.
Like the Krell KSA 50, 80 etc.

I don't really get the association of SE with large units, other than
the necessary heatsinks.

You're not thinking of Nelson Pass' Son Of Zen designs, are you? ;-)
