Isobars aren't designed for audio and may impede sound quality.
Why? I have my Sony Digital turner, a digital clock and the two Acopian power supplies plus music server switching power supply plugged into a Isobar and haven't noticed any sonic benefit or degradation.
As a matter of fact, I have never noticed any sonic benefit or degradation, zilch, nadda, from using any filter or distribution device from the Adcom ACE-515 Power Enhancer, to different variations of the Felix filters to the Isobar. But my electronics have never been zapped by electrical surges either so they must be doing something which is the reason I use them in Tucson, AZ, one of the lightning capitals of the world. During non-lightning days the preamp and amp are plugged directly into the wall.
