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

Thank you for all of this intel!!! Keep chiming in.  It seems we have to look to China for alternatives given the war in Ukraine, and China looks to be upping its offerings.  

I've been using the Linlai Elite from Grant Fidelity in my integrated amp and they sound really sweet. I tried them in the Freya + and they were OK but sounded better in my integrated amp. The Shugang WE 6sn7 were also OK in the Freya but a little congested in the bottom end. Just received some PSvane 6sn7 from Viva Tubes and they will need a lot of breaking in. The sound was restrained from top to bottom. So far, the best is Silvania 6sn7's. Great tone!

Running Linlai 6SN7 tubes in my Supratek preamp.  This tube runs circles around the stock tube.  Also put this tube in my Black Ice hybrid preamp.  The Linlai is a stellar tube.

Thanks all.

@jaymark Jaymark that is high praise!  You also have very nice preamps!

As a follow-up, I just received a pair of Linlai E-6SN7s.  Right out of the box (oh, they come in a beautiful box) they sound really good.  I'm very curious to see if they break in. They sound particularly smooth and warm with just a right amount of air on top new.
