Is the KAB Fluid Damper worth it if...

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.

james,

it looks like the dayton isolation cones are now $25.19 + shipping for set of 4 if I am not mistaken which product to order.

I will try this since its so much less than the mapleshade

NO, not the ones at $25.19. I meant the ones they market as speaker spike/cones--the first four selections here, where they differ only by color. For example, for black chrome, you'd get this set for $22.88 for a set of four plus shipping.

These include m6-size threads which makes these brass cones a low-cost screw-in replacement for the Technics feet.

Of course, as Tvad said, you then need something to couple them to such as an isolation platform.
