I haven't had the 440MLa, but did own its predecessor the 440ML. I found it to be noisier than average in terms of scanning previous damage on record grooves. I use an M97xE on one of my turntables and love its sound, tracking ability, and handling of warped records, but while a bit better than the AT, it's not the quietest I've heard, either. The vast majority of stereo styli have had a 0.7 mil cross section (.7 mil conical, .2 X .7 mil elliptical, etc.), so these will all track at about the same place on the groove wall. A .5 mil conical would ride lower while a .2 X .8 mil elliptical would ride higher, and either might avoid contacting previous damage and thus make a record sound better (unless you have records from previous owners who wore out there records with .5 mil conicals or .2 X .8 ellipticals). A line contact stylus doesn't ride lower in the groove to get below the damage; it rides above, below, and in the middle. There is an excerpt from a Stereophile article below that explains why line contact styli can increase rather than lower our hearing of surface noise.
I've found a Grado to be lower in noise than some. They no longer publish stylus size information, but they used to say their elliptical was .3 X .6 mil, which might ride below some previous wear. A couple cartridges I've been meaning to try but just haven't yet are the Sumiko Black Pearl, with a .5 mil conical, and the Sumiko Pearl, with a .2 X .8 mil elliptical. With a different published cross-section, these might have the best chance of avoiding previous wear and both are priced at less than $100.
http://www.stereophile.com/reference/170/index7.htmlFootnote 12: Changing to a different cartridge can sometime work sonic wonders with old records, due to the new stylus riding on a different, relatively undamaged part of the groove wall. On the other hand, changing to a cartridge with a long-contact profile, Microridge or van den Hul, for example, can often increase surface noise and the reading of groove damage due to the stylus's being in contact with more of the groove wall.—JA
