Best Tubes for Raysonic 168?

Hi Sam,
They are the 6922-E88cc bought from Upscale Audio so for the cost I will assume they are real?
Thay do work well though.
I found the good old Mullards to be a bit to rounded but very nice,just too much of a good thing for my taste.

Regards,Bob

Not a question of authenticity only of manufacturer, I think many OEM's had tubes labeled with their brand name that were manufactured by the big names and there in lays the hunt!

Thank you everyone for your input! Unfortunately my tube rolling has come to a halt. My 168 just stopped working and is on its way to a repair facility. The last tubes I tried were Russian Rocket logo 6H23 from Upscale Audio. I thought they sounded great in the bass, ok in the mids but not much sparkle in the highs. When I get my unit back I will continue the tube rolling

Sorry to hear that, let us know what happened to your CDP and when you are up and running again!!
As a side note from Tom_hankins experience I tried Bugle Boys in the S/E (my I/C are S/E) and Orange label A frames in the bal sockets, I'm extremly please with the sound!! thank you TH!
Best of luck with your Ray.
Sam
