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

@hifinut51 I also found that the MP3 benefits nicely by upgrading the 12AU7’s. Like most system components in our hobby, synergy is key and the sum of the parts many times exceed individual components. The RCA black plates 12AU7’s are a good example and when paired with the RCA black plate 6SN7 make a very nice combo.

@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.
