“I don't know. They didn't harm the sound at all. The idea is to help reduce vibrations that can adversely affect the sound of some components. I think and hope that the Bright Star IsoNodes are helping with the sound of my stereo system, but I have no idea how to objectively rate them.”
“These feet are quite effective. By now they are old technology... but I've yet to see anything better even close to this price point. They DO absorb vibration very well. I also use them at work under my cheapo Onkyo CD player (because it has a headphone amplifier it's ideal). The bouncing and skipping that occurs because of the desk is radically reduced.”
“Work great under a Rotel CD player as well as some portable CD players I have. And work great under blu ray players. The difference is there and noticeable.”
“Great vibration absorbing feet. Much more compliant (squishy) compared to stock rubber feet. Much more effective at keeping vibrational noise at bay. Isolating each individual component doesn't make a big difference that you notice by itself, but collectively, on all the components, you get a lower noise floor and less background noise. It's shocking how small nuances in music become apparent as the noise is reduced. The individual instruments and musicians seem to separate and become more distinct.”
“While these feet were as specified, they are a bit pricey for rubber type product. They support the amp just fine. I cannot tell any difference in sound with them or without them. But YMMV.”
