Linlai E 6sn7 tubes

I now have about seven hours of play time.  I sat and listened for 5 minutes after the first 1/2 hr. My first impressions were exactly what I was told to expect,dark, no sparkle. I also noticed a very narrow soundstage.  I’ve been running mid 60’s GE 6SN7 GTB for the last month or so. Prior to the GE’s, I was running a pair of Brent Jessee KenRad vt231 black glass. The KenRads have been my reference tubes thus far.( I’ll be putting them back in after proper burn in of the Linlai’s) 

      I just sat down to have a listen,and the darkness is starting to fade,and the soundstage is becoming wider and deeper.  They are starting to show promise.

I agree with @atmasphere that Sophia should be avoided. My experience with their customer support has been terrible.

My Linlai tubes arrived just recently, haven't had time to try them yet.

Thanks to @rocray for bringing these to my attention.

Just ordered two for the Don Sachs Model 2 linestage. If they sound as good as expected, I’ll order two more for the remaining spots. Looking forward to hearing these.

Does the size of the glass affect sound in any way? If a company puts their normal size tube guts into larger glass, will it automatically perform better?

Thanks,

@vinylvalet,and @aldnorab, I’ve been told they need 100hrs of burn in. Please post your impressions here. I’m at about 55 hours. I m on vacation,so I’ve been running them 12-14 hrs a day. I haven’t done any analytical listening,but they are definitely filling in from first listen.

     @aldnorab, I’ve read in advertising copy about the shape of the glass affecting sound. I would have to defer that question to those more knowledgeable than myself.  

@rocray  thanks for the break in info. Mine are on the way from China and will take time to arrive. Will update their progress as they break in. Previous Don Sachs Model 2 linestage owner set it up with two gray glass RCA VT 231, two Ken-Rad black glass VT231, and a Coke bottle Sylvania 6BY5GA rectifier. If Linlai can match or beat this and have a long life, I'll be thrilled. Looking forward to your break in updates.

 How tall are the Linlai? Hope they aren't taller than the Sylvania rectifier. It is twice the height of a standard 6SN7.

Thanks,
