So I got a great deal on some Shure M447s a while back. It was two carts for about $80 which if you know anything about how Shure M447s prices have been being gouged lately, that’s a steal of a deal. I decided to try out the Ortofon Qberts, but I kept having problems with both when trying to beat juggle. The needle would end up skipping and with control vinyl, it would start drifting toward the outer edge of the vinyl/platter. I finally realized recently that the screws and nuts I was using for the carts I have were not being tight enough. I found a nut or two that would tighten the Ortofon OM Qbert cart to the point where it was rock solid and immovable on the headshell. Once I did that, the drifting to the outer edge issue went away completely. The cart is more stable and it does not skip. It’s a night and day difference. No matter what I did with the previous screws/nuts, it would not get extremely tight so I thought that was how all carts were. That’s not the case and you want it so tight you can’t move the cart on the headshell not even a centimeter. I’m pretty happy with the Ortofon OM Qberts now and see no need to get the Ortofon VNLs that are releasing soon. They look like Shure M447 clones but they don’t have as high an output as the Shures. Between the OM Qberts and the Shure M447s with Jico Stylii, I’m good on carts for the forseeable future. I even have some Ortofon OM Pro S carts for backup. Long story short, get those carts secured as tight as possible and work from there. If you need better screws/washers/nuts, check out your local Home Depot or at worst, Amazon.com. Perhaps on one of my pages I’ll put directions on how to properly set up a DJ turntable for turntablist DJing. Peace and stay up!
