Linlai E 6sn7 tubes

@pinwa good to hear.  I've only had the stock EH tubes, which were way to bright for me.  Then tried some JJ's, not bad actually but not great, then Sylvania VT231, which I have liked quite a bit.  Tried a combo of JJ in 1, 4, and Sylvania 7N7 in 2,3,5,6 and have liked this so far.

Just bought a quad of the E-6SN7 from China and will see how those do in 1,2,4,5, if I like them I'll buy them for 3 and 6 since I do use my dac with XLR but it also has RCA so I can still test it without getting all 6 tubes at once.

@blkwrxwgn I bought my SLP-05 used and it came with the stock EH tubes.  Maybe they were worn out but I really disliked them.  Actually thought about selling the SLP-05 until I changed them out.

It has never been clear to me if you need to have a matched quad in 1,2,4,5 or if you can have one type in 1,4 and another type in 2,5.  It sounds like you had good results mixing them?

@pinwa had great luck mixing them up, I was surprised. But yeah those stock tubes are horrible. I think people sell them with the stock tubes because they never used them. 

All I can say is I put a pair of Linlai 6SN7-E tubes in my Audio Mirror Reflection monos a couple of days ago and WOW. What great tubes, period. Not even begun to break-in. I immediately ordered a back-up pair. Every thing said here about them is correct, at least in my system. 

Same here. Added two to my Cary preamp and just the two for the balanced output and noticed an immediate change. Nice airy highs and separation. 
 

ordered a quad that will arrive Monday and will have all 6 tubes be the Linlai. Excited.
