Forgive me for not exactly answering the question, but, with so many opinions expressed here, I thought I might chime in. The best description I've heard re: c-j comes from fellow Audiogoner; Zaikesman, he described c-j as being "sunny". I have to agree. To me c-j is warm, yet not dark. C-J's tend to roll off the extremes, soften the transients and yet maintain midrange detail. The ss c-j's can be a little lean in the bass, the tube c-j's a bit over ripe in the bass. The c-j ss pre's can add just a tiny hint of sharpness in the lower treble. C-J's have the unusual talent of maintaining sparkle while avoiding brightness. I also find that c-j amps tend to add a certain burr to the sound, not enough to loose detail, but enough to deviate from neutrality. On the other hand, they maintain harmonic integrity. No gear is perfect, and c-j's faults tend to complement the music, certainly better than the all too common alternatives. FWIW,IMHO,YMMV,cliche',cliche',etc..
