Grant Fidelity Treasure Globe 6SN7 SE

hi,
wondering if anybody has tried the Treasure Globe 6sn7 se from Grant Fidelity?  The whole Psvane, Shuguang, and now Grant, is confusing.  It sounds like a dysfunctional family where everybody went there own way, but they all copy each other and use similar names.
The best 6sn7 I’ve heard is my Psvane gold base/grey glass big bottles.  Wondering about the new globes from Grant?
Any info appreciated! Thanks, Ted

We did a comparison and IMO they sounded very similar- and both excellent. However, the globe structure has a decided resonance that the Linlai does not. As long as you don't have microphonic problems its no worries, but any microphonics the tube has/might develop will be exacerbated by the resonance of the glass

Thanks very much for the response, @atmasphere!  You mentioned they sounded similar.  Do you recall any specific differences besides the potential for microphonic issues?

I'm writing to "second" the question by the OP.  I'm surprised no one has answered as I'm sure there are a lot of 6SN7 users out there and a Linlai 6SN7 thread discussing a similar tube is going like wildfire.  Does anyone have any experience with these tubes?  I'll try to paste a link below showing the Grant Fidelity page that lists both the Treasure Globe 6SN7 SE as well as the Linlai.
