EL34 SED, Black Sable or Genelex Gold Lion?


I am currently using the new production EL34 SED, bought from tubedepot.com, and are very pleased with the result in my Manley Snappers. However, I am curious and still searching after new constellations of tubes in my amps. It is part of the fun. And here is my question:

Have anyone compared the EL34 SED with the Black Sable edition of the same tube?

And, how is EL34 Black Sable compared to the Genalex Gold Lion KT77? (almost the same price)

Any experience with these tubes?

My eperience ( my system ) with the SED Cryo'd El34 is that they do not sound the same ( or as good ) as the stock SED El34..Point being they sound warmer ( quite a bit ) and not quite as much air..If you need more warmth,thats a different story,but if you systems tone is where you want it, the Cryo'd El34 would not worth the extra fee.. Some tubes do sound better after Cryo treatment but my experiance the SED El 34 isn't one of them..Keep in mind this is to my ears and my system..

Thanks Thorman. Your descriptions is exactly what I am after. What about Genelex Gold Lion compared to SED, anyone?
Musicophile : Check with ( Search ) Jim McShane tubes ..Jim has a great reputation for his tube Knowledge and Selling and sells both tubes your are interested in... From what I can gather the Genelex G/Lion is a more Linear ( or more neutral ) tube than the Stock SED EL34 ...So its always kinda what " Tone " you are looking for..I have treid quite a few EL34 ( have not tried Genelex yet ) quads and always come back to SED.......Good Luck..Hope that helps..
Anyone compared the Golden Lion to the Siemens EL34? Is the Siemens more detailed? Tried to post this 2 times already but the system seems weird.
