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?

No. Only one swap.

Yes, only switch one. If you run multiple sources, leave the cartrige leads alone and switch the + and - speaker leads. That way all the sources that the pre inverts phase gets corrected. Some will tell you that phase is over rated due to the lack of recording standards.

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.
