LinLai WE 300B or the LinLai Global Elite Permaloy 300B tubes ?


I presently am using Sophia Electric 300B mesh-plates and find them to sound good in general.  I originally used the Sophia Royal Princess 300B's and really loved the sound, however in my experience, reliability was really poor and for the price, it wasn't any fun trying to get replacements.  I'm getting ready to order new 300B's however would like to know if any of you have had experience with their WE 300B or their flagship Elite Permaloy 300B.
Thanks... John

It appears Psvane has new Acme 300B tube out, looks like punched plate vs solid plate for other Acme, priced about $200 more than original Acme. Can't find much info out there about this tube, anyone heard it or have more info?
@liquidsound, any further developments on LinLai tubes? I'm getting very close to pulling trigger on 300B purchase. Coming down to EML XLS, Linlai Elite or one of the Acme iterations.
Just received 16 WE 300B tubes for my Canary Audio Grand Reference Mono Amps.  Waiting for further directions from Canary before installing them.  I hope they sound WAY better than the Golden Lion.  
I haven't done any listening for the last two weeks as I've been laid up with COVID...  Sucks !  So I've no update on the LinLai 300-B's ...
@liquidsound,
I hope you have a full recovery and zero lingering after effects.

@willgolf,well that's quite the investment but that amplifier deserves top tier tubes. I'd be surprised if you do not notice a substantial improvement with the Western Electric 300bs.
