I see these battery backup UPS systems made by APC at CompUSA and they go up to 1500 Watts for about $200.
Here's what I was thinking. If the APC is all charged up and you unplug it from the wall, would you get really good sound from low-current drawing components like the CD Player or Preamp since you would be supplying power that isn't picking up interference or ground noise ???
Has anyone hooked one of these up to there audio system and can tell me weather it improved or degraded the sound?
If this is all wrong, does any company make a "powercell" that would power audio components with isolated clean power ?
i can't comment on aps' ability to improve audio. i know ps audio make a power cell device which they clame improves audio. i think they sell for $400-$500 and have four outlets on them. i have no experience with them. i just know they exist.
