AUDIOPHILE RIDDLE
What's better than a hockey puck?
(drum roll please - cymbal crash)
Two hockey pucks!!
I discovered this by accident after installing two new amps. I was moving a speaker switch to a new location on my rack. It was previously under one of the amps which I had elevated with double HP to create the requisite space. The other amp had my standard one HP for mechanical isolation. For some perverse reason I installed extra HP under the amp with only one. I went into the other room to listen and make sure I had wired everything correctly. I was greeted with a sound that I did not believe these speakers capable of delivering (brand and model shall not be revealed, too embarrassing!).
Off to the sporting goods store to buy a few extra bags of HP. Six HP in stacks of 2 under a component's chasse, not under the footers, but please experiment. Six under the preamp, amps, universal player, tuner, turntable isolation platform. Eight under my subwoofer spikes, I use two on top of my fiber optic converters, and five on top of the woofer cabinet of a speaker to quell some resonances. I have a single one under each leg of my steel equipment racks. I put 5 1/2 HP between the platter and tonearm of my Pro-ject RPM 10 and quelled some subtle resonances that I am sure they addressed in their subsequent redesigns.
While I am at it I have found folded doormats without backing are ideal for light weight pieces like linear power supplies and Furman power conditioners.
I have 90 HP and four folded rugs at work. Visually inconspicuous, effective, and dirt cheap. My kind of tweak!
