Rather than decouple, try coupling using ceramic or brass cones. I found it to bring sharper focus to upper mids and highs.
Do I need to decouple/isolate my preamp amp from my stand?
I have long wondered if some devices under my preamp and amp would be worth the effort and price.
I am currently using some old rubber balls in delrin cups on my preamp. Don’t seem to notice any difference.My amp designer (Ralph of Atma-Sphere) tells me that anything under the M-60 mono blocks will not make much difference and stay with the stock rubber feet. Although he says that something under the preamp is needed. I currently get excellent improvement using Stillpoints under my speakers. The improvement is tremendous! But, obviously, a clearly vibrating box needs something to decouple it from the floor. It is not so clear under the components. I am about to buy some Stillpoints Ultra Minis at $375 for three and try them under my preamp. A pretty expensive experiment. Mike
