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,




The tubes from Viva also had the ringed base as the ones from Grant Fidelity. The lettering was different & the sound from the Viva’s were not as refined (open) & were base shy.

Hi @danmar123, my point was that the ones you bought from Grant Fidelity has the ringed base, but the one that is pictured on the Grand Fidelity doesn't.   The fact the base of the tubes you got from GF look identical to the ones sold by Viva might suggest that they are both manufactured by Linlai but with different letterings.  But as I mentioned earlier, Linlai would not acknowledge the ones with the horizontal letterings.

It's good to know that you do hear differences between the ones from Viva and Grand Fidelity.  I wonder if the ones sold by Viva and other Chinese retailers are rejects that didn't meet the tight QC requirement, and hence sold at a lower price.  Just another guess.  The mystery continues...

Thanks, @danmar123, I appreciate your response!

It would be interesting to hear any other feedback on the Linlai Global Es - especially comparisons with other tubes - and perhaps including thoughts on the bass region.


The tubes that’s are being sold at Grant Fidelity are very high quality.

@lowrider57 Well if they didnt acknowledge, then its hard to tell.  But the way its packaged, is quite identical to the Globals. My guess its manufactured for different markets.
