Sophia Electric KT88-ST impressions

I've had a pair of the SE KT88-ST in my amp for a short time. 75+ hours of play time.
They perform better than everything else I have here. Gold Lion KT66/77/88. PSVane 6CA7-Z'S black bottles. Wide open mids. More linear performance from top to bottom. Great extension at both extremes. Balanced and musical. And, I'm using them in an ampsandsound Mogwai. 3 single-ended watts into 8 ohms. Time will tell re: reliability and longevity. 

Any else tried these?

If we're talking coke bottles there's a very positive review on positive-feedback.com 12/10/2016.

@dmhenley  thanks for posting your impressions. If anyone hears the Sophia Electric EL34's myself and several others here are eager for feedback.

I've added the SE 6SL7 to the fun. I compared it to a couple nos tubes I have. Posted on the site. In general, a similar experience in that the SE tube sounds more linear, open and maybe with a slight bit more gain.
