EL-34: JJ Tesla or Electro-Harmonix?

A group of us (Mechans, BadBoss429, Audiogon dealer Quest For Sound - Stephen Monte, and a few of our other cohorts) recently conducted a 3 step Tube Shootout that I'll write up here on Audiogon one of these days using the following:
JJ Blue Glass E34L
JJ KT77
ElectroHarmonix EL34
Mullard EL34 XF1
JJ Blue Glass KT88

In my opinion, if you want the best EL34 made today, it's the JJ E34L.

Currently, in my Jadis amp, I'm running the JJ KT77. Far more powerful low frequencies than the E34L, but the E34L's midrange is much better. More or less a question of which you want more.

In the end, I'm just going to have both on hand, and switch between them based on the music, mood, etc.

Interesting, 1markr!

In our shootouts, in three different systems (mine, Badboss429's, and Audiogon dealer Stephen Monte's/Quest For Sound) the JJ E34L and JJ KT77 sounded nothing alike. One would probably not expect they were made by the same company, as normally I find tubes have a definite house sound. However, the JJ KT77 sounded more than a bit close to the JJ KT88, but with superior mids.

We also tried the 1960s Mullards, I'll write the findings up in a thread here soon.

I was hoping we'd be able to try the SED tubes, but no one had a set to put forward.

It's nice to get a lot of different perspectives here, as it broadens the understanding of the tubes. Guess the old adage of system dependence is at work...
