Phase Inversion on CJ equipment

Hang on; some CJ preamps do not require you to invert the phase to have your system be "phase correct". On my CJ (solid state) preamp, only the moving coil phono stage is inverted, which can be corrected by reversing the wires on the tonearm going to the cartridge. There appears to be some confusion here. ARGENT: WHICH CJ PREAMP DO YOU HAVE??? You may want to contact CJ to clarify if you are not sure. They usually respond to eMails within 24 hours.

For the rest of your question: In a lot of cases with high end audio, "Less is More", so if a stage of the preamp is used only to make the unit phase correct, removing it removes a possible source of distortion. On my Stan Warren modified DVD player, Stan removed part of the output stage and replaced it I think with a couple Blackgate caps as a buffer. It means I now have to turn the volume up a little more, because the output is a little lower, but it is also a lot cleaner than before per Stan.

The explanation that Bruce gives parrots exactly what CJ describes in the 17LS manual. A phase inverting component is a bit unusual in the audio world which is why CJ points it out so explicitly in their manuals (and conversely, points out that the Premiere amps are not phase inverting). Simply follow the advice in the manual for the preamp and things will work correctly. I'm also surprised that your preamp is phase correct -- I was under the impression that all of the CJ preamps were inverted. Live and learn.

As for playing CD's, I haven't found quite as many phase inverted CD's as metaphysics estimates, so correct phase alignment in the system overall is generally important for best sound. Which of course begs the question as to why an engineer would invert the phase on a CD in the first place, but that's another topic...

I was speakig of the CJ tube pre amps. I have no knowledge of their solid state units so I would take Sugarbrie's advice and consult the manual or e:mail CJ. I have always found them to be very responsive.

I have the PV12L, no phono stage. I think I stated the manual incorrectly.

On Phase inverted Compact Disks, I've read that reversing the speaker wires won't help you. Something else in the signal path needs to be changed. The Rotel RCD-990 CD player has a phase inverting switch on the remote. I've also read that phase inverted CDs sometimes happens by accident.
