Linlai E 6sn7 tubes

Does the Asian market like tipped up high frequencies? 

Hey Ray,  I guess as long as you're happy with the sound.  That's all that matters.  I was doing it for my own curiosity.   

Anyway, these Linlai might just be a tad too tall for my setup, so I haven't really decided whether to go ahead and purchase them yet.   But I'm definitely interested in looking for good sounding new production tubes and not relying on NOS tubes.  Who knows when the supply of NOS tubes will eventually dry up.

Hey @audioquest4life, your guess is as good as mine.  😀

This is way too confusing. Authorised dealers such as Viva Tubes and Don Sachs's distributor only sell Linlai's with the horizontal lettering. Unfortunately, all of Don's pics show the Shunguang tubes. I can't believe that these horizontal branded tubes that sound so good and have terrific build-quality are all counterfeit. The fact that Linlai didn't comment on said tube is perplexing.

Linlai and GF's websites have identical layouts, product photos, and descriptions. There's no question that they represent the legitimate products. I wish Linlai would publish authorised dealers instead of only stating who is not. 

I just went back and reread some comments on this thread and found this from @danmar123 

I been buying from Viva for years, that's why I went & purchased the 6sn7 from them. The tubes they sent me, did not look, or have the same sound signature like the one's from Grant Fidelity or China. ''First hand experience''. Viva received them today & refunded my monies in full. I'm sure I'll be dealing with them again, unless I'm on their BLACK LIST....

That sounds consistent to what I read on the Global Linlai website.   Since Grand Fidelity is the only authorized 'global' retailer,  then probably the tubes from Vivatubes are sourced from tubes made for the Asian market.

Hey @danmar123, question for you.  Which tubes sound better to you?  My guess is you probably like the GF tubes better?
