Depends on how you like your pasta. Endless combinations and permutations of gear rendering same number of acoustic palettes. I've several systems running and like them all. I've owned several tube pieces, same with SS. There is no RIGHT. There's better..... and worse. But no right. Like finding the 'right' Monet.
I like tubes, but tired of the endless chase to re-tube, upgrade the tubes, wonder if they were still strong enough. For me, SS, really really good SS ended that quest. For me.
And I moved away from the richness, romance if you will of that tube sound and moved to immediate hard hitting live sound. No listening fatigue, just live. For me.
Enjoy the journey.
