VPI cartridge install f/phase inverting pre


Classic manual says that, "if phono section inverts phase, hot color becomes the ground color". My pre (w/phono) inverts phase, but I've already switched the speaker cable leads for this. So, do I still need to swap cartridge wires or is this now unnecessary?

Thanks!
If the owner's only source is a TT, does it matter if the change is made at the cartridge (as VPI instructs) or at the speakers? I wouldn't think it would matter.
I have a CJ pre that inverts phase, I swap the + and - at the speaker's end. All my sources are hooked up to the pre. So one swap at the speaker's end is enough. Also, you can tell if it is out of phase by listening.

No, it does not matter, though changing speaker leads is probably easier than changing the cartridge leads.

My preamp inverts polarity, but so does my CDP, so I invert the leads at the phono cartridge and leave the speaker cables alone.
Aaahhhh, now I understand. Wasn't aware that there were cdps that inverted phase. thanks
BEWARE you have to check whether your phono or line stage invert phase.
If the line stage inverts then change the phase on the speaker cables.
If the phono inverts phase then you need to change the cartridge leads otherwise your other sources will end up out of phase.
For diehard analogue fans I have found inverting the phase at the cartridge end ( if phono out of phase ) sounds better than inverting at the speaker end.
