Linlai E 6sn7 tubes

@invalid, yes it is. Make sure you’re looking at the E-6SN7. It is their ELITE series. 

@laaudionut I haven’t tried the Shuguang Treasure 6SL7s yet, but I have tried the PsVane CV-181 (6SN7) TII which are very similar, if not identical to the ’guang Treasure CV-181. I can assuredly state that the Linlai Elite 6SN7s blow the TII 6SN7 Treasures out of the water. I don’t know if the SL7s will match up the same, but my gut says the Linlai’s are superior tubes. You can purchase Linlai from Grant Fidelity in Canada, or for quite a bit less from a reputable seller on eBay "kt88_6550" whom I’ve purchased from more than a few times with excellent service.

It seems the Elites have been flying under the radar for a while. I’m hoping durability matches their sonics.  I haven’t seen much on long term reviews. @aricaudio, do you have any insight? 

I purchased some of the Linlai E-6SN7s from Mable Audio last year. They arrived really quickly and in good shape. http://www.mableaudio.com/en/productview.asp?sid=10229

@rocray I haven't had an opportunity to put more than 200 hours on 2 sets of the Elites as I was only burning them for customers to send with their preamps. However, out of all of the Linlai tubes I've tested and used (more extensively were there DG series 845s, Elite 2A3s and baseline 5U4Gs), I have not heard a tic, pop, or any other anamoly whatsoever. This is out of well over a dozen pairs tried. I cannot say the same for many of the top tier PsVane tubes I've used, and that's all I'll say about the PsVanes with the exception of their ACME 211s.

I hope this helps, Aric
