Linlai E 6sn7 tubes

Hi @danmar123,  thanks for the info.  Very helpful.

Just curious, did you get the 'Global' tubes from Linlai directly or Grand Fidelity?  If they're from Grand Fidelity, did you get their "Top 10% Ultra Low Noise" ones for $40 extra?

Thanks.

@xcool , I ordered from LinLai in China & they sent my order to G/F.

Yes I purchased the top of the line, "ULN" so there was no 2nd guessing.

OK, I see.  Thanks @danmar123.    

Just to refresh my evaluations. The bottom line is: I had the 2 different tubes at the same time. There is a difference between the Global & the non Global in my system. Why don't members just try for themselves @ the cost of return shipping. This would stop all the inane posturing that's being discussed about these tubes. This weekend I changed Carts on my GAE from Hana ml (240) hrs. to my Cadenza Black (83) hrs. on an SME 309.

With the Globe's, my system has NEVER sounded so good. I have K/R, Sylvania JAN & Tong Sols, tried every combo & with the 4 Global in my Don Sach's their staying.

@danmar123  Maybe I missed an earlier post, but this is the first definitive proof I've read about the difference between Linlai tube types. I don't think there was any posturing going on, only speculation.

Thanks for weighing in.

And after buying so many NOS and "almost NOS" during the tube panic, I couldn't afford an expensive pair of Linlai Globals.
