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


Which 6SN7 tubes have you tried and which one was your favorite?

Also, what's the best place to buy it?  Best service and best price?

I ran RCA black plates in my MP3 for a while (until they went noisy) and liked them very much. Nice lively 60’s rock and roll sound, if that’s what you’re into. I believe Tube Depot has them in stock.

@immatthewj  “60's rock & roll isn't my thing”. Beatles, Stones, Zombies, etc., etc., etc.  What’s not to like.  I guess I’m showing my age 🙃.

@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.

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