So I replaced a pair of 6N1P-EV i used for a past week with my CSP3 with cyro treated Telefunken E88CC, same one as I said earlier I'm using as single one I was using and noticed that they added some body to the bass which is noticeable on string while listening Beethoven's 5th. I tried 2 rectifier tubes Valve Art 274B and Mazda 5Y3GT and while I like both I think that with Mazda highs are a little bit smoother and little bit better clarity. I also ordered RCA 5Y3GT black plates and Jan Sylvania 5U4GB so will see if they can make any difference for me

The beauty of the CSP line is great sound with endless variety via tube rolling.

Yes...totally agree, but with a caveat.  The HD800, HD650 and T1 sound great out of the CSP...but it is worthless with low impedance headphones...for that you need to get the Decware Taboo!

  tried 2 other recirtifier tubes I got with CSP3 while still keeping all 3 Telefunken E88CC's and finally can agree that Philips 5R4GYS is the best I have tried so far but it wasn't the case when a pair of 6N1P's or Genalex golden lions' where used instead.

Also have a quick question. Just discovered that  sometimes volume of right channel is low while left is fine. Slight move of input tube solves problem but I want a permanent solution. Will "socket saver" do the job or sending it for repairs is the only option?

Update: Just found out that I can hear musc o r sometimes hum in right channel even if both controls near single input tube are all the way down

You could try cleaning the sockets and tube pins with deoxit. Might be a little buildup or some oxidation. A pipe cleaner and the cleaner can get into the sockets pretty well.

I tried to clean socket with deoxit using provided brush but it didn't help plus it happens with every tube , Telefunken just got from Upscale Audio a week ago
