I've never owned a cart that even approaches this in terms of track-ability, smoothness, and removal of sibilance and inner groove distortion.

A lot of records suffered from the dreaded inner groove distortion, not all, but many

The 400MLb gets deeper into the groove to pick up the sound better, and has less inner groove distortion.

My experience with this cart (anecdotal of course, your mileage may vary):• INNER GROOVE DISTORTION (IGD

The OM-5e was far from junk and produced very good sound with one big exception: horrible inner-groove distortion

After years of listening to LPs with the Shure M97xE (sometimes swapping out for a Stanton 680), I was always bothered by the harsh inner groove distortion that plagued most of my records

To my ears, the sound between the 440MLa and 440MLb is indistinguishable: both have a bright, slightly "punchy" sound, but both also eliminate that dreaded IGD (inner groove distortion)

I was blown away by the major reduction in inner-groove distortion; I don't think I can even hear any distortion at all now

The AT100E suffers from the dreaded IGD (inner groove distortion) that most lower-end carts do
