I have the JJ EL34, E34L, and KT77. I find it amazing how so very different these three tubes sound.
Personally, I like the E34L best. It offers an absolutely glorious midrange, as good as any tube I've come across. The problem is the weak low end. The KT77 is my least favorite, though not bad, and sounds closer to a KT88. The EL34 offers an interesting sound, nice from top to bottom, with nothing sticking out in a good or bad way. The surprisingly decent Shuguang EL34B sort of mirror the JJ EL34, and though it's close I'd say I prefer the JJ.
A week ago, I finally broke down and purchased the JJ big bottle 6CA7. I won't get to them in the immediate, but I've long been curious to hear them.
