I keep reading messages suggesting that newbies like me choose MM cartridges instead of MC. I am confused as to why. I am just getting into vinyl for the first time in 40 years (back when a Zenith changer was hi-tech for me). I ordered a new turntable and phono stage and it will arrive today. However I ordered a MC cartridge to be factory installed on the turntable (Rega P8 with an Aphetta 3) and an Rega Aria phono stage. Did I make a mistake as a newbie by going to a MC cartridge? What is the appeal for newbies to go MM instead?
