Linlai E 6sn7 tubes

@audioquest4life  May I check if the Linlais you were referring to as detailed are Linlai Globals with vertical letterings or Linlai E6sn7  with horizontal letterings as @lowrider57  has outlined. As you may have read in this chat, there are different impressions between these two tubes. 

@audioquest4life Apparently Yes. If you go up the thread, there has been a lot of discussions about this. @danmar123  feels there is a difference. Some have found the non global Linlais pleasing. Others like @lowrider57 do not feel its up to mark.  You can check out the posts. I have purchased similar tubes as yours  and am still burning it in. 

I just got my Ken Rad Vt231 black glass. Am  pairing it with my Linlais. I have the KRs on the buffer stage. Seems pretty ordinary to listen to right now. Havent felt the bass depth or  slam that is often associated with the KRs. Sounds  a bit warm.  Is it a case of burning it in? How long do these KR tubes take to burn in? Or should I put the KRs on the gain stage?  Or is it a case of poor matching as in the Linlais dont match well with KRs? My Linlais have also not been burnt in fully yet. Perhaps I should match the KRs with my Sylvania GTBs.  Any one mixed and matched Linlai E6sn7s  with KRs or KRs with Sylvanias. Appreciate your views.

@lowrider57  and @rodman99999  tks for the reassurance. Yes I need to be patient to see through the break in.  Just that when I got the KRs I was expecting at least some change from the onset. Well I will run  the tubes further and see how it goes.

@rodman99999 No worries. Yes I have had pretty good bass depth and slam before  in my system especially in solid state.  Even with prior  tubes,  bass wise (not as good as solid state) but the tightness and depth was somewhat there; not as good as I wanted having been used to my solid state bass production, but pretty decent. Slam was allright too. So naturally, I can feel the difference.

@rocray  Happy for you! Enjoy the sonic bliss!
