What's the best 6NS7 tube you have tried in your Atma-Sphere MP-3 preamp?

@elrod did you ever have a problem with the DC offset LED’s staying on when using the Shuguang tubes? I have not tried Shuguang but I have tried other large bottles and in both cases the DC offset LED’s lit up much too much to my liking. Rather than taking a chance I removed them right away, so I don’t know if they might have settled down after a while or if it could have caused a problem.

@marco1 , I didn't say that there was anything wrong with it, just that it is not what I listen to. now.

@immatthewj understood, it was meant to be tongue and cheek. Sorry it didn’t come across that way.

Not in pre, but my amp.

Been using a 6F8G for a month now and like it.

About the same as the Ken Rad but tightened up the bass.

From Don Sachs whose electronics use 6SN7's octal tubes.  He has heard most every variant of the tubes and concludes this:

 "In my gear, I use Linlai e series or the Shuguang WE6SN7plus.  The best tube I have ever heard is the new Ray tubes select 6sn7, which is pricey."  He is believes these Chinese tubes are superior in SQ to a lot of the pricey NOS tubes.  He admits that he has not heard the new WE 300b tubes, which might be better, but are extremely expensive.
