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,



Can anyone comment on this?  With all the reviews I've seen on the Global Elite E version, this is the first I've read where it may "accentuate the hi frequency spectrum at the expense of bass". 

He may have been referring to the Chinese E-6SN7 and not the expensive Globals. I sent him a message asking which tube lacked bass.

Thanks, @lowrider57!  Please let us know if you hear back. 

This may make sense based on the info from @pindac on the last page. The Linlai Global website includes the following phrase describing the Global series:

...without exaggerating the ultra high frequencies (much of Asian music does focus more ultra high’s and Asian audiophiles are accustomed to such a type of sound).

This seems to hint that the Chinese domestic version could have a brighter tonality.

I finally pulled the E-6SN7’s from my amp and installed them into my preamp. What I was hearing before was influenced by tubes in the other stages. Now I hear the sonic signature of the Linlai’s more clearly.

First off, it’s an incredibly quiet tube. No noise or microphonics, I tapped on the PCB and nothing. There’s usually some sound from my NOS tubes. The bass doesn’t dig deep, I’m hearing a more pure sound than when it was in the amp. Highs are extended but not tipped up, no harshness. It’s neutral and there’s a good presentation of tonal colour plus a wide soundstage. The mids are linear and nothing special.  Imaging is focused, but not 3D (and I’m using Melz 1578’s in my amp. I understand why they sound good in the Freya and Sachs preamps when used with a complimentary cathode follower.

The cost of the Global E-6SN7 is prohibitive for experimentation, it’s equal to a good pair of "NOS" tubes. Now I wonder if the Global HIFI (entry-level) tubes are worth a go.
