The only ones I've tried are the Gold Lion KT66. I read quite a few reviews before buying them. They were only a few bucks more. But can't say which sounds best in an Inspire.
I'm sure vintage 6L6GC, like RCA black plates, would sound great too. I have just two GE 6L6GC and so can't make that comparison. Or you could break the bank and go for the original NOS Genalex KT66.
