The Mapleshade feet to get (if you get'em) are the Threaded Heavyfeet at $40 each, or $160/set for a Technics.
A-goners who have them like them a lot. I'm not sure if anyone has had the smaller Dayton cones and then upgraded for comparison. I am guessing that the Mapleshades would sound noticeably better than the Daytons. They almost certainly would sound different, as the heavier weight would change the mass loading, vibration paths, and resonant frequencies.
Ditto for the Isonoe footers. Some have Mapleshade cones; others have Isonoe footers at about the same price, but I don't know of anyone who has tried both.
