Linlai E 6sn7 tubes

@decooney, it appears that the Psvanes are definitely cut from the same cloth. First off,you are far more eloquent than I am!  In comparison to the Linlai’s,the blue globes seem a tiny bit rolled off on the top end,but definitely not dull.  I find the low end to dig just as deep,but with just a little on the flabby side, but not sloppy at all. These are also very quiet,just like the Linlai’s.  I think they do a good job of projecting a 3D soundstage,just not quite as wide as the Linlai’s.  I totally agree with you about having more options out there. I have no issue with running these newly manufactured tubes vs vintage. Of course, I’m not going to commit to not buying vintage tubes. ;-)

Not noticable quiter in my setup.

@rocray for comparison, I would not characterize the bass on the Gray Glass / Gold base CV181 MKII Psvanes as being tight or super fast either. It’s not flabby, yet slightly more on the "bloomy" side, which I like. I have been sort of looking for this bloomy character with various 6SN7s too. In my experience this character also tends to bring nice lower midrange tones along with it. Something I prefer with my all-tube system. All part of my intentional moves away from analytical solid state sound past 5+ years.  The best part about tubes, tuning the sound.  

@decooney,bloomy was the term I was looking for. 

My 1st pair of Linlai 6sn7 are at 75 hours. Thankfully they have lost the shrill & brittle sound. They are engaging now, with more body and more open high. The soundstage is back and there is more decay. The high frequencies are more extended, but still not as floaty as the RCA. I could live with these, even if they don't improve further.

I do wonder if the 2nd set will displace the Ken-Rad or be too much of a good thing? They have entered the country. Can't wait to hear how this pans out.

Thanks,
