Tube rolling experts!!!


Hi guys,

I am looking for advise based on your experience with these particular tubes in my components.  

I own a Raysonic CD128 since 2009. The player came with 4 Russian 6922 EH tubes. I don't know what's the average life span of tubes or when they start to deteriorate from their optimal performance. The player is used sparingly, may be no more than 500 hours over last 7 years. Is it time to replace stock tubes?  

The second components is Modwright Elyse with Phillips NOS 5R4GYS Rectifier and Tungram PCC88/7DJ8. Is there anything else out there that I can experiment for substantial boost in sonics?

I am after that lush midrange and extended top end. More air around the instruments, but stay away from anything that overly 'bright'.  

The associated components are Krell Evolution processor and Modwright KWA150SE (both solid state). 

Thank you for your time!

I have the Phillips 5R4GYS and Telefunken E88CC's in my Elyse and love the combination.  I did have to send my Elyse back for an issue which was fixed, I included the Telefunkens which Dan compared in his lab, his comment was they are very good.
I got the platinum grade + CRYOGENICALLY TREATED.  I'm not really sure if the treatment does anything sonically but its only $8 so why not.

Has anyone tried the Amperex 7308s? I have been curious about this tube too.
