VPI cartridge install f/phase inverting pre

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.

I've never seen or heard of a preamp with a built-in phono
stage, where ONLY the phono stage inverts phase? Usually
it's all or none, but maybe they do exist?

My Cary SLP-98P F1 has a built in phono stage. The phono stage is non-inverting, the line stage IS inverting. My CDP's output is also inverted, so I invert the output of my cartridge, and run my speaker cables non-inverted.

Jmcgrogan2...according to the SLP98 owner's manual, BOTH the
line and phono are inverting? I used to own this preamp
with phono and never recalled this difference. That's why I
looked at the manual.

From the manual, (page 11):

Amplifier – Speaker Connection

 The SLP 98 (line and phono) preamplifier is phase
inverting.

 This will require you to connect the positive
speaker terminal to the negative binding post
on your amplifier. The negative speaker terminal will
connect to the positive binding post
on your amplifier.

This is very common in older tube preamps, each 1/2 tube gain stage inverts phase and if you have an odd number of gain stages in a stage, it usually ends up inverted. It is not uncommon for either of the line or phono to invert phase.
Pays to check the manual.
