Why do MM cartridges amplify more surface noise??


My concern in the thread is mainly moving magnet cartridges, not MC's I recently purchased an Ortofon 2M Blue MM cartridge which sounds very good with minor exceptions. Prior to the Ortofon, I briefy used an Audio Technica AT120E.

Unfortunately, the Ortofon seems to reproduce much more record surface noise than the AT120E which was remarkably quiet, except on very noisy LP's in my small collection. Without a doubt the Ortofon 2M Blue is a much better cartridge than the AT 120E

So what causes one MM cartridge to provide more LP surface noise than another?? Is it stylus design or materials, or the windings inside the cartridge body?? Is it heavier tracking force??

What MM cartridge in your experience reproduces the least amount of record surface noise??

I don't think its a MM vs MC problem. You would need to listen to a lot more samples to be able to say that's the case. I can think of 2 things that might cause your problem. First is the shape of the stylus. I know that has an effect on how much surface noise you hear. The other is break in. Phono carts break in a lot. Way more than any other type of component. They almost always sound bright/harsh when they are new. As it breaks in, the highs tend to smooth out and not be so pronounced.
