In Reply to: RE: Will a dedicated AC line fix a ground loop? posted by firstname.lastname@example.org on June 25, 2008 at 11:03:09
Interesting question about grounds, etc. I just recently had a dedicated 20 amp grounded outlet installed and with all components plugged into it, it sounded worse than when they were all plugged into a two conductor non grounded outlet. The house wiring was so bad that there was not a ground on it before this new line was installed, along with a new panel and 3 other service lines including A/C.
I've been told on the general forum here that it takes awhile for the new romex, connections, etc. to break in. I've put the stuff back and am only powering the power amp with the new dedicated line. The preamp/cdp are plugged into a power strip with the TV that goes to the old 2 conductor line. I THINK it sounds better now, but not sure. Will have to listen carefully for a week or so and then try something else. Filters? Ground lifts? Everything back on the dedicated line?
...but based on my own situation, yes, it's great to be able to plug the notorious RF polluters into the old outlets, and keep the dedicated line pristine.
...But yes, too: the dedicated line made everything worse except for the stray voltage discharge leaking into my hand every time I touched the front aprons of my amp or preamp. Mercifully, that much is fixed now.
Seriously: I could start a believe-it-or-not museum with all the ridiculous (and sometimes inexplicable) problems I've had. I thought they were all attributable to ungrounded outlets causing fault energy to fry internal components, but I just bought a Marantz DVD player and it quit working properly on the second day out of the box.
I'm skating perilously close to giving up on the whole thing and getting an Aiwa bookshelf system and downmixing the 5.1 input.
Who is on a mission? I guess I am. From time to time, though, I've done what you suggest. Just drop back to some modest equipment and forget about the equipment for awhile.
With a recession/depression looming, now might be a good time for that.
On the one hand, we'll be able to pick up some pre-owned stuff for uber cheap -- but, on the other hand, anything that doesn't work out for us will cost us even more than usual on re-sale.
