It's easy to test for inter-channel phase shift if you have a preamp with a mono switch. All you have to do is play a mono record while engaging and disengaging the mono switch. If you hear the cymbals and other high frequencies become reduced in volume when engaging the mono switch, that indicates you have high-frequency inter-channel phase shift.
I've noticed this only on a very expensive cartridge. My cheap cartridges were just fine. I owned a $4000 Dynavector XV-1 that exhibited a noticeable reduction in high-frequency volume when playing a mono record and engaging the mono switch. All my cheap cartridges had no such problem. When I say cheap, I mean cartridges costing between $300 and $1000 such as a DL-103R, DL-S1, AT-OC9ML/II, AT33EV, etc. The high-frequencies on these sounded just fine when engaging the mono switch. Therefore, I got rid of the Dynavector XV-1 and vowed never to pay more than $1000 for a phono cartridge.
HW wrote a post in 2004 about measuring inter-channel phase shift using a Lissajous pattern on his oscilloscope. He said his inexpensive Shure cartridge produced negligible phase shift but some other very expensive cartridges showed significant phase shift. He refused to identify the expensive cartridges.
Good luck,
John Elison
