“Using these small feet under my Oppo BDP105 disc player which I use as a CD transport and music streamer and also under my PS Audio DAC. I was concerned about the vibrations from the CD motor affecting the Oppo's performance, but these tacky sorbothane feet seem to do a great job of damping vibrations in the chassis. Ditto for the PS DAC. Do not let the low price fool you these do a great job of isolation”
“These completely eliminate the vibration that I can see and feel in my Marantz DAC1 headphone amp which I also use as a preamp. Before using the Pico feet I was able to see my Velodyne subwoofer vibrate the DAC1, but no longer.”
“This is a very good isolator. Make sure that you get the right ones these are for lighter-weight gear like CD players and preamps. I use mine under my Oppo blu-ray. There's a subwoofer not too far away and I was worried about the vibration. The BIG question is can i hear a difference? Yes, I hear a subtle improvement in clarity. I'm using the Oppo as my music server into a Musical Fidelity DAC.”
“Do these things work? I would say "yes.". The improvement is subtle but it's there especially if you have high-end gear. For a cheap boom box these are a total waste of money.”
“Bought these to use lighter weight components to isolated vibration for a clearer cleaner sound on tube system. If you want to really want to hear what everything really sounds like, this is a must have accessory.”
