With this in mind, it seems using RCA cables would make for the most direct signal path and better sound quality. Curious as to you guy's thoughts before I invest in more cables.
None of my sources are Accuphase, so they are the standard XLR pinout design used with gear here in USA. I currently have been using balanced cables throughtout and select "invert phase" on the preamp. Maybe going to nice single ended cables throughout would be the better option?

C-275V:
the input and output circuits are balanced, the potentiometer is not.
XLR polarity is inversed (2=inverted, 3= non inverted).
When using non Accuphase sources you can select the output phase of the C-275V. However the audible effect might be very small or even imperceptible.
P-1000:
the input and driver stages are balanced, the output stage is not (just push-pull).
IMHO the sound quality is more convincing with balanced cables, provided the cables are absolute top notch.
Try to get some demo cables from a dealer and compare for yourself.
