Guitar players talk about 6ca7's as being "scooped" - that is, mids turned down, like a smiley face EQ. That's been my experience running them in a Dynaco ST70 with a dynamutt octal mod. A lot of folks like that sound, as it focuses more on bass, but I don't. It's like mids and upper mids are missing. Actually, EH EL34's sound really good to me - a lot of upper mid and high end detail, but bass is there too. My wife thinks they sound "scratchy". I guess it all depends on your gear, what you listen to, how well your ears work, and what you want to hear.
To further confuse the issue, there are KT77's, which to me, are kind of in between 6CA7's and EL34. They sound scooped also, but have more high end sparkle than 6CA7's. I haven't tried E34L's or JJ's EL34 II, but, reading between the lines, seems like they lean toward 6CA7 kind of sound.
Just today, a set of JJEL34's came from Tubedepot. I'm listening to them in the Dynaco now. They are pleasant, but definitely darker-sounding than EH's. They are supposed to be the brightest of JJ's EL34's. It will be interesting to compare them with EH EL34's once they are broken in.
Read something last night about using the output tube type your amp was designed for and am exploring changing feedback circuit to accommodate different types of tubes. The fun never ends...
