A well recorded mono LP is an attention getter.
Period press of straight ahead Jazz on Contemporary, World Pacific and Riverside are a few of the other labels that do the magic.
Might be more trouble than it's worth, but you can "strap" the phono outputs if your system doesn't offer a mono switch. With a mono switch strapping is then done in the pre-amp. What I do is run two turntables in two different systems. The dedicated mono unit is 1, an e-bay and then overhauled Pioneer 1150. The Pioneer runs the Grado MC+ (there is a new upgrade MC+), the other, 2, is a Pro-Ject Debut Carbon DC with a Audio Technica MC cartridge through the P-J S box, that cart has since been obsoleted and supplanted. You can play mono with a stereo cartridge, each side of the cart will feed "stereo" outputs to your system. I have noticed the effect you mention when playing a Shibata stylus. Do not play your stereo records with a mono cart. For Jazz and Classical I prefer Mono, it gives a more "sitting in the front row" experience for me, not to mention going back to the days of mono systems.
