What's been your experience with New Chinese 6SN7 tube options?

Shuguang is out of business due to a fire at their facility. I'd love to try their tubes, but due diligence is required because the available stock for sale are leftovers and may not have good test results.

This is a long read, but lots of info about buying Linlai 6SN7 tubes.

Really like/love the Shuguang WE6SN7 replica tubes in my Dennis Had Inspire headphone/preamp and use that piece in both modes. Bought a set off ebay from a Chinese vender with great results and after the plant burnt was able to buy a slightly used pair that were sourced from Grant Fidelity as back ups.

I recently bought an amp that uses 6sn7 and have been doing the required (extensive) research.  A friend who I trust says the 6SN7-SE Treasure Globe from premiumvacuumtubes.com is the best 6SN7 he has ever heard.  I do trust his opinion a lot.  $225 ea.

I'll be watching for other opinions on this thread. thanks.

I have had great luck with the Linlai Elite E6SN7. This has turned out to be my go to tube in my preamp.
