to properly judge any mat you need to somehow insure it is not moving around even a little. if one is stable but another less so you won't know what the mat itself is actually doing.
maybe some double-backed tape, Elmers Glue, or light spray of artist's glue. something that lays perfectly flat and insures the mat will not shift at all.....and can be easily cleaned off without issues.
i'm using the Boston Audio Mat 1 on the 301 and it sounds better since i secured it. i have not compared the Boston mat to anything other than the stock 301 mat; no contest the Boston Mat is better. the Boston mat is made of a particularly slippery material and does slide easily on a metal platter.
