 @roberjermanA friend of mine had a the Ampzilla Amp
sound great with Infinity RS Kappa 8s
Threshold SA/4e, 350e, S500 w/optical bias and a sweet Jon Soderberg upgraded SA/3.
I’m using 2 mono-block tube amps I built from schematics published in 1958, from books my father had and was going to throw away. Switch Mode Power Supplies. Modern passive components. All RCA tubes. The finest amps I’ve heard. Class A 45 Watts/channel. Tube phono preamps.

The only heat comes from the filaments. Granite bases.
