Opinions Please - New Prodduction Sophia EL34ST Coke Bottle

@ jond

Have you heard Gold Lion KT77comparisons to any of the Psvane or Black Treasure line that Grant Fidelity imports. I had the GL KT77's operating in a pair of Primaluna PL 7's, and  remembering liking there qualities.
I am considering upgrading the current JJ E34L tubes operating in my Ars Sonus Filarmonia, hence the Sophia inquire. Since there around $500.00 for a quad, I was hoping to get some opinions here on AG.
What ever I find out, I will pass along. I contacted Sophia regarding there construction and where they manufactured, only to get a response on how the tube was in great demand and on a month back order. Normally my pursuit would be minimized after a factory response like that, but I once owned a 274B mesh plate that I substituted for a Russian 5AR4 in a Woo Headphone amp and the improvement in SQ was everything I was hoping for and well worth the cost. In addition to my experience with the above referenced rectifier, I would like to hear opinions of others who have heard the EL34 tube.

Thnx
Brad

Your observations of the Psvane EL34 Phillips Holland replica, and KT77 comparisons to the other tubes you reference is helpful. Thanks for the input.
