Tubes for Raysonic CD 168

I have a Raysinic cd 168 tube cd player which is using the Electro Harmonix 6922 tubes. I would like to hear from other Raysonic owners as to what tubes they are using and what it did to the sound. The rest of my system is: Classe 15 amp, Audible Illusions Modulus 3a pre with 6h23eb tubes, Vandersteen 2ce speakers. All interconnects are mit terminator 2 and speaker wire is also mit terminator 2. Power cords and conditioning are courtesy of Shunyata.

I'm not good at articulating tube virtues (or their lack). When I stick in a pair or
quad of new tubes my reaction is totally subjective and comparable only to
what I've preferred before. Sure, I listen for the usual stuff -- openness, clarity,
dynamics, bass, balance, etc. -- but more important is "Does it grab me?
" The 6N1P tubes definitely grabbed me for a while but in the space of
several months I was ready to try something else. That said, they're definitely
worth hearing, and so inexpensive it costs practically nothing to do so. But the
Bugle Boy 6DJ8s show me all that good stuff noted above plus the level of
"involvement" (trite, but can't think of a better word) that no others
have delivered over time. To me, in my system (Aesthetix Calypso linestage,
SET monoblocks designed and built by a friend, Gallo Ref 3 speakers and
subwoofer amp, Morrow Audio cabling).

Thanks, "involvement" is a good bottom line description!! I think I know exactly what your saying I use Amperex 6DJ8's in the Joule amps(sometimes Amperex 6922's or 7308's but whenever I try any of the Russian tubes it seems they all have a thin grainyness to the sound, very bothersome, and I can't get the Amperex's back in fast enough. The same was true with the Ray 168.
As a side note when I had the Calypso I used Amperex 12Ax7,D and Halo getters, then tailored he sound with the 6922's.

Mike In Md:

The 6CG7 will work in the Raysonic without alteration. I've never had a problem in any cd player that uses 6922 cathode followers, swapping for a 6CG7. Including Raysonic. The poster was looking for a lush tube sound. I gave him an option. 6N1P tubes also work without altering " play with the circuitry (reset the bias, plate load resistors, grid bias, etc.)." But 6N1P is not a lush sounding tube.

Also, in the Raysonic, all 4 tubes will have an effect on the sound from both xlr and RCA outputs. You can mix and match the tubes in pairs- inner and outer.

No desire to argue about circuitry etc. So please refrain from replying on that subject.

Please do reply after you have tried the swap for yourself.
