Linlai E 6sn7 tubes

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?  

Hey @lowrider57,  Linlai Global does publish their authorized dealers here.   Right now there is only one listed, which is Grand Fidelity.

@xcool, I just read the disclaimer on the Linlai website.  They constantly refer to the tubes as Linlai Global.  No where on my tubes is “Global” used.  After a visual inspection of the Global tube on their website,vs the tubes I have, I can notice no difference.  Now,this isn’t saying there isn’t a difference, just I can’t notice any.  I’m now interested in a side by side comparison of the Globals vs the version I own. This is interesting to say the least.  The only Chinese writing I see is on the gift box. No Chinese writing on the tube. All this being said,doesn’t make me not like what I’m hearing,and I’m still impressed with the sound quality once burned in.
