Which EL34 is your favorite and why?

Golden Lion KT77's and I've tried them all.

I also recommend GL KT77 for their rich midrange but also a nice tight bass

simna,

Here's a link to Brett Jesse's EL34 website page which, aside from being his listing of tubes he has available, provides his listening impressions of various tubes, you may find this helpful. Also, you can look up similar info on his website for the other tubes you are after. My only affiliation with Brett is as a satisfied customer

opps here's the link

Ditto on the Gold Lion KT77s...after using KT120s, 88s, 6550s, KT150s, and JJ KT77s in a single ended pentode Dennis Had amp (with various rectifier tubes involved), the Gold Lions knocked me out. An amazing 77 that especially compared to the JJs are simply far superior. My faves so far.
