For me, I want a couple of really good sounding 1:1 interstages, SE so

best handshake possible!!!

I'm sure I'd want some as well, if I knew what they were. :-) Probably
just as well, because they sound very expensive.

Interstage transformers, as used in the distant past to couple the signal
from the anode of one valve to the grid of the next. They went out of favour
in the 1930s when higher-gain valves made RC coupling more useable.
