Signs of poor electricity in home...?


Ok folks I know pretty much that all homes have crappy power for electronic gear. However my dilemna is that I have continued to have a buzz type sound come from my spkrs whenever amp is powered on. This is the same case with three different amps and a recvr. I just completely disconnected everything and have all the gear everywhere in the living room. This was no small task.

Nht Power 5
Nht Power 2
Oppo 83
Toshi HDDvd
AudioControl Bijou EQ
Panamax 5500ex
Nht A1 x 2 for bi-amping mains.
Nht X2

I use Signal pwr cables and my own custom made.

I have eliminated any cable combo as the culprit and have it narrowed down to the fact that with an amp plugged in, powered on, and just spkr cable connected to a spkr I get this slight buzz/hiss type noise. I mean nothing connectected to amp but what I said...electricity...and spkr cable direct to spkr. It is not the hmmmmmmmm of 60hz...it's a hiss like white noise makes when a tv channel would sign off-air if you are old enough to know what I mean. Anywho...it's bugging me to pieces. I have went to the breaker box in garage and eliminated it being the fridge in neighboring room, etc. Even with the Panamax it still gets noise to the spkrs mid/twtr...mainly mid. Volume has little or no effect on it if you are wondering.

So????? Dirty house power and what do I do. Would having a seperate/dedicated line help? I don't have dimmer lamps or any other of the typical buggers in the ac chain. No tv either as I have a Pj setup which plugs in where I use to have a ceiling fan and installed box/receptacle to pwr it.

I don't hear it if source is playing but sitting idle all 5 spkrs doing this is annoying. Suggestions please.

I would install an eight foot copper ground rod. Attach it with lightening ground wire and clamp to your main breaker box. This can be bought at Lowes or Home Depot for less than $50.00 bucks. Having a good earth ground helped me with a noise problem at my old home. I installed one when I moved into my current home. It is real easy just use a garden hose to soften the soil as you drive the rod into the ground. When you get the rod low you switch to a sledge hammer to finish.
There is a ground bar or spot in your breaker panel to connect your earth ground. If you do not understand please do not experiment. There is very high voltage in the breaker box which can kill you. Maybe if you get your bar in the ground which is the hard part you can get the power company to connect the ground strap to your breaker box. Slip the guy a twenty. Once you get a good earth ground things will be quieter.
