3 Dedicated lines into 1

I had three dedicated lines run from my main panel when my basement was finished. I am still getting some hum even after putting in cable ground loop break and plugging all my components (other than main amp) into a Monster power conditioner. All of these helped but I think the remaining noise is because the amp and Monster are on different circuits. Does anyone think combining these circuits to be on the same line would help? I know very little about power but it seems that I have read that this could be causing my problem.

I have also thought that having a seperate ground put in and putting all three of my dedicated lines on it might have a good result. Any thoughts on this?

Thanks

cheater plugs on every component except for your preamp. that cures 99% of all ground loop problems. saved me.

Yes that can be a problem due to unequal length grounds of multiple dedicated circuits causing a ground loop hum. Experiment by trying everything on a single circuit & see (hear) what happens.

First thing to do is take the monster out and plug all componets into dedicated lines, then take a cheater plug and use on amp only, should solve your problem and if it does reconnect everything back into monster.
Cheater plugs are crap so a better thing to do is to modify a dedicated power cord for amp. most of the time it's one componet that cause the hum so you may need to swap the cheater plug around until you find the componet thats causing the hum but most likely it's the amp.
Good Luck!
