In my experience cones are just fine and dandy under speakers, but with electronic components, they isolate but add a resonant peak (including Audiopoints, BDR and many others I have tried). Better to deal with electronic components with a top quality rack and shelf, and forget fancy footers. Every damn one I tried had some beneficial isolation effect, but also added a persistent coloration that was unacceptable.
Isolation Cones. Will I get the point?
I have them on my Thiels and the difference is significant. Will putting appropriate isolation cones on my amp and CD player make as much a difference? Or any difference at all? Why?, if you know. I would appreciate feedback from actual listening experience. Please: tell me what you heard, not what you heard of. Thanks
