Would a power conditioner help?

Posted by Mark Tinordi (A) on April 24, 2007 at 00:54:56

Linky

The above (click "free" on the right column) is the background noise to my phono preamp. I remove my computer's power cord part of the way in, which is the quiet part, then replace it (when the noise cuts back in). There's a bit of hum and radio interference regardless but unplugging the computer kills most of the noise.

I can't plug the computer in anywhere else; all of my stereo is plugged into the same power strip as it out of necessity. Would a power conditioner eliminate the power line noise or is it due to something else? I don't want to drop a few hundred without knowing that it might help.

And should I get one for my whole hi-fi or just one of those two-outlet dealies to plug my computer and a power strip (with the stereo) into? I have a two-watt 45 amplifier so it's hardly starving for power (two watts, even into medium-efficiency speakers, is plenty loud enough for me, by the way; your results may vary but it's amazing how little I needed the other 148W when I moved down from solid-state).

I'll be glad to answer any questions that might help.
