Linlai E 6sn7 tubes


I just placed an order for a pair of these for my Aric Audio Motherlode II.  I’ve been chatting with a fellow that runs the E 6sn7 in his Don Sachs pre. He loves them, He says they make his NOS tubes sound thin and lifeless.  
    It will be a couple weeks until I receive them,and I was curious if anyone out in Agon land has tried these,and what are your impressions?   
Thanks in advance,

Maybe @vivatubes can clarify why there are physical differences beyond just a branding issue.  

I know Linlai says there is a difference between eastern and western bound tubes, but I bought mine from a Chinese dealer and they look identical to the ones from Grant Fidelity, besides the logo is a little different, so maybe viva got some early issue tubes or later issues. I would be surprised if they weren’t both Linlai elite tubes.

@decooney, thank you so much for bringing up that issue with your signal tubes. After reading your post,I remember that I read about that phenomenon some time ago. I am going to give that a try.

I had an issue today that my power supply tubes were not firing up. I contacted Aric. Buy the way, what absolutely wonderful customer service!! He responded within 20 minutes,on a Saturday,on a holiday weekend, on a product I bought used.
He had  me replace the fuse, and the rectifier tube. The Motherlode II is now up and running. I put the Linlai’s back in,and got that distortion”grunge “ that @decooney mentioned. Now to try to tap that grunge away.

Received my Grant Fidelity Linlai Globes today. Superb tubes.

They are extremely quiet, more quiet than the best Linlai I have had so far and as quiet as the CV181’s I have in the hiss/tube rush category.

I did have to use an extender on one to keep them from touching front to back on my preamp.

One whole hour so far. Very happy with the purchase.

@bugredmachine  Good for you! Tell me; do they have the same sound signature as the ones you sent me?
