CJ does this because they would have to add another stage to the preamp to make it phase correct. Adding things to the signal path usually only makes things worse. Some Blue Circle preamps are this way also. My phono stage is out of phase for the moving coil connection for the same reason (less is more). The moving magnet stage is in phase. This is corrected by reversing the wires going to the cartridge.
i live in pelham,ny. if that helps.also i have a carver 500 T amp that the cj pre is fronting.i don't know if the amp is inverting or not.if it is ,i probably don't have to do anything.does anyone know if this amp inverts? thanks. and thanks for the many replies.i love all this info.
The Aesthetix Io phono stage is true balanced. Offers the traditional balanced out jacks, plus the options of phase normal and phase reverse via dual pairs of single ended RCA jacks.
