I was a machinist before getting into management about 30 years ago. That said I am fortunate enough to have some precision metal cutting equipment in my basement & the ability to use it. I made aluminum "tip-toes" about 25 years ago & used them exclusively under all my equipment up until about a year ago when I tried the DH cones. That was certainly an improvement which led me to try some other things. In the last 6 months I've made a few dozen different footers of various materials. All of them use bearings. I've found in my limited experience that various different materials in the same footer yields the best results. As Robert (who has a lot more experience than I) states above, everything makes a difference. I find that fascinating & am not done with my quest yet. Bottom line is footers can transform a quality high end system. That was something I wasn't convinced of until I started listening to different configurations.
Isolation footers for amps
I'm looking for advice/recommendations for isolation footers for my amp -- an Audio Research D300 (solid state). Currently I have it mounted on a free-standing 4" thick maple block, with spiked-tipped brass footers anchoring the base to the carpet on top of a basement (cement) floor. Would I obtain any additional sonic benefits by placing after-market isolation devices between the amp and the maple stand? I should add here that I'm not looking to spend a great deal of money on this... something more in the range of $100-200. Options in roughly that range I've found on line include Audio Prism Isobearings, Herbie's Tender Footers, and Mapleshape's brass footers. My (perhaps imperfect) understanding is that the first two are meant to isolate a component from vibrations in the room (including those from other components), while the third is supposed to help 'drain" vibrations from the component in question itself, thereby minimizing their transference to the audio chain..
I'd welcome advice from fellow Audiogoners more experienced than I on the extent to which these devices confer audible sonic improvements and, if so, which ones they'd recommend. Thanks
