"In my experience, there is a spacious dimensionality in high-quality tube amps that I never quite hear in SS amps of the same caliber / price range. Texture and tone, particularly in acoustic and wood instruments. Also, the assured warmth without loss of lucid definition. And today’s good tubes don’t suffer from labels such as "slow," "tubey" or from any background hiss. Certainly, SS is easier to manage at all the points we all know... I went from British SS amps to tube amps a while back, and it’s hard to go back. But I’m always listening for good SS as well... Recommendations?"
I generally agree but there are exceptions.
You should hear Bakoon amps.They are incredibly 3D sounding Class A/B.
I have owned and used some pretty decent SETs and other tube amps and the Bakoons at least match them for deep layered soundstage and ambience.
