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.
