Why not just buy a Sugden amp and end it. You will no longer have a yearning for anything else....read up on Sugden, they were the first with SS Class A in 1967. No BS class A that transitions to class A/B....I had not even heard of Sugden, but a few years ago. My curiosity peaked, and I broke down and bought one. It set me back a decent penny
..but man I’m glad I did it.....A21SE Signature...once that was in place, I again broke down and purchased my Tannoy Speakers, now I’m in the poor house lol. I’ll tell you what, it’s one heck of a combo. You would not believe how good only 30 watts per channel can sound (40 watts into 4 ohm). I’m pretty much set for life, as I’m old.
