A:AnswerThe model number you provided is for that of a direct-drive turntable that does not use a belt, please check the model number and resubmit your request.
A:AnswerYou need either a receiver head with built in amplifier which most all do have OR a dedicated amplifier. I use a small 100W per channel amplifier. The turntable will not drive speakers alone. The turntable has a built in pre-amp which in turn drives an amplifier.
A:AnswerEither, but there would be no advantage in replacing the cartridge as it is the same cartridge internally that you have now. If you replace the provided green elliptical stylus with the AT-VMN95ML red Microlinear replacement stylus, you will now have the equivalent of an AT-VM95ML Cartridge.
A:AnswerYes it has a pre-amp. If receiver does not have a dedicated phono input it’s no problem. You can use other or auxiliary inputs. You may or may not have to switch the turntable to pre-amp or line out.
