Thank you for all your responses. I have a Pioneer Quartz PL- 550 Direct Drive Turntable.
I also own a Mobile Fidelity V-LPS preamp, which allows me to use MM or MC cartridge. Since I'm also getting a fully refurbished Pioneer SX-850 receiver, I wonder about the safety and sonics of using that receiver with two cartridges, one being the Denon DL-110 and the other the A-T, as described above. The receiver has two phono inputs and I'm struggling how to make them all work together.
