I've been slowly upgrading my system (interconnects, cable, components) and I'm almost at the point where I am considering a power line conditioner of some sort. Right now, everything is running off of a power cord (like one used for computers) to prevent surges. What about other stuff? I've seen some audiophile type of wall outlets which, I presume, provides a better connection to the power line. There are "plug" type things that look like AC adaptors and they just plug into wall sockets. They are supposed to reduce interferance in the house electrical system. I'm not sure if I believe their claims. I've seen battery type components where the system runs off a battery and recharges itself. But I don't like those as eventually the battery will expire. And there are true line conditioners. One of them converts the power from AC to DC and then back again. There are many brands out there. Does anyone have any recommendations for line conditioning? Anything that does or does not work? Thanks in advance for your help!
