Jez, just so you know, your “oh dear…” and following opinion are completely condescending and patronising. We all have ears and are entitled to reply to the opening question with our own experiences.
As per thread title, all the class A amps that I have tried didn’t meet my expectations. I admired their tonality and sound staging but their lack of cohesion and “snap” spoiled the music for me. It all sounded a bit too separated and lacking in joy.
Those who make silly statements may get "condescending and patronising" replies! I assure you there is no class A sound! Whatever you didn't like about the amps you've heard had diddly squat to do with them being class A.
I'm sure there are A/B amps you love and some you consider to have a "lack of cohesion and “snap”, but in those cases you'd say you didn't like "Acme" (whatever had the lack of cohesion and “snap”) amps, and not blame it on the amp being A/B.... 'cos you know an amp is class A you've grabbed the wrong end of the stick and run with it
TLDR: If all amps were class A there would still be ones considered "Pratty and dynamic" and ones considered "pipe and slippers"
