speaker cable static sound

Can anyone help with a technical question:

I am using audience au24 speaker cables ( I believe they are unshielded) and there is a tv nearby. The problem is that even when the tv is not on or even plugged in I sometimes get a mild static sound coming out of one of the speakers. The weird thing is that its only out of the right speaker even though the tv is equidistant to both speakers. The other weird thing is that the static sound does not immediately happen when I turn on the amp but comes after a few minutes and will often just go away and then come back and then go away.

I have tried lifting the cables off the ground and moving around the monster ac outlet strip. No, none of the audio equipment goes into the ac outlet strip nor do they even share the same wall outlet.

I like the speaker cables but maybe I should get a shielded cable? Any recommendations. I currently used purist interconnect dominus between amp and preamp and use the emmlabs dcc2 as preamp and dac with their cd transport. My speakers are Wilson Watt Puppy 7's.

Thanks

I did try changing the speaker cable to a purist speaker cable that I was borrowing and got the same static.

HOWEVER, I just tried last nite a different outlet strip for the video component and got no static even when I put the tv on. I will keep trying this older outlet strip to see if the problem was with the monster video outlet strip. It seems weird that the outlet strip which is older and cheaper might solve the problem but hey its worth a shot.

Metro, if the outlet strip idea of mine does not continue to work......I will try the other thing you suggested that I boneheadedly did wrong.

Thanks Guys For the Help!

p.s. I contacted LAMM and they are going to analyze the problem too . They believe however that the problem is not with the single tube in each of the mono hybrid amps

Karmapolice,

Sorry that I'm not familiar with all your audio equipment.

Are both amps plugged into the same wall outlet, and/or outlet strip? If so, it's beyond my 40 years of electronics how malfunctioning strip protection circuits could single out any "matching" components plugged into it.

Anyway, you could also try running both amps into the same wall outlet directly, and the remaining components from another outlet (via extension cord) for testing purposes. My feeling is that your problem will return, but please continue with any recommended diagnosis.

Sadly, the static did return....am awaiting the advice of Lamm and Metro04 I will also try your other idea that I blew but ran out of time today so will try tomorrow.

it's going to be either the amp or the speaker.
also contact wilson audio for advise.
I think when you switched speaker cables from Nordost to AU24 you could have shorted something momentarily. Do you remember if your amp was off when you changed the speaker cables?

Well I found the area of the problem

I switched the left speaker cable to go into the right side amp and right speaker cable into the left amp and the static moved to the LEFT SPEAKER.

So there must be something happening with right mono amp since its the only variable that switched the static to the left speaker.

Its weird though that it only happens on occasions and comes and goes intermittently.

Its only a little static too .......strange........Hopefully Lamm won't need the amp back
