Best current EL34 tubes


I need a matched quad and noticed that the svetlana. Electro-Harmonix, and JJ are all about the same price. Which are the best ones to buy for natural sound accuracy? Thanks for the help in advance.

I have been getting excellent results with JJ tubes. I've been using the E34L the longest and prefer it to the KT77 for the way it reproduces the midrange. But if you are looking for natural sound accuracy, I would definitely recommend the KT77. I have not heard the SED tube.
are there any el 34s which are euphonic, i.e., attenuate the highs and have some "bloom" in the lower mids ?

i have a tube amp which is a bit too focused for my taste.
