Linlai E 6sn7 tubes

I am burning in the new Linlai E 6SN7s. These are in my Aesthetix Io phono stage. so far, so good. I am liking what I am hearing and what I am not hearing, bland, rolled off or muffled sounding, etc. 

I can’t say these are a night and day difference to the Russian 6SN7s that came from the factory but the soundstage and imaging are great and frequency response seems to be even handed, nothing bloated or exaggerated. Bass still feels deep and taught and midrange vocal resonance sounds extremely realistic. My impressions thus far are that they are a decent replacement. Perhaps I might experience more profound changes after some tube burn in. At the end of the day, if you are looking for a modern 6SN7 tube, this may be it. Now, that being stated, my system sounds superb as is with the tubes I am using and these tubes contribute to maintaining the same sound qualities I cherish. Can’t go wrong there. 

Danmar123, I think I also emailed them, I also bought 61np from them Vivatubes.comTo be fair they ship fast. But if I were to buy tubes I will buy from Grant Fidelity, I believe they listen to their tube and their tube quality is next to none. Pricey sure ? But you will get high quality tube.

@jayctoy I been buying from Viva for years, that's why I went & purchased the 6sn7 from them. The tubes they sent me, did not look, or have the same sound signature like the one's from Grant Fidelity or China. ''First hand experience''. Viva received them today & refunded my monies in full. I'm sure I'll be dealing with them again, unless I'm on their BLACK LIST....

@danmar123 

Yours is a difficult situation to figure out. Could your tubes have been for the Chinese market, or grey market US? We'll probably never know. 

@lowrider57 the tubes I had were from ''bugredmachine''. I tested them for him. If you go back to one of my posts, I said, they made my Ortho Black open up. If I remember correct, they where from Linlai. Hopefully I'll receive my tubes in a few weeks..... Any day now, any day!
