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!

274b is  a rectifier made specifically for Audio 
The Emmisions lab 274b is a true mesh plate and hand made a fantastic improvement in sound but $275  you power supply needs to be able to handle 3 amps . I use Lundahl transformers in  mine. You can also look up thd Emmisions lab 5u4b also  $275 just look it up and look at thd build quality this true mesh plates produce a much more 3 Dimensional presentation.
I have used several Mullards ,RCA   as well as Shugaung  which the preferred series are actually very hood for under  $35. Best of luck

I have tried Siemens Cca, Siemens E88CC A frame, Tungsram E88CC, Mullard E88CC Parasol Getter, Tungsram 7DJ8, and Phillips Miniwatt SQ (made in England) in my Modwright Elyse.  I like the Phillips the best, great midrange, great base response, and balanced top end.

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.

azbrd, so far 2+ on Telefunkens. I am sure they are every bit good but also expensive. Just as much as Phillps miniwatt SQ. 

Thank you!
