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

Hi,

I cannot bypass the preamp because my preamp is also my dac and the transport does not have volume control.

There is also no preamp to source cables that are left channel right channel. They only are digital cables that control the data and clock

I did just cross the ic cable not completely swap them. But again I had previously used the valhalla nordost cable and was experiencing the same problem.

The problem began when I switched speaker cables in January 2006 from Nordost Red Dawn to Audience Au24 speaker cables.

Karmapolice,

Sorry if this responce comes through again, but didn't think it took.

Anyway, the IC cable crossing was to inject any right chnl static into the left amplification and speaker. If static continues from the right chnl, and you've exchanged the speaker cables as stated, the only remaining items are the amp's right chnl and speaker.

Switch the speaker cables at the amp, and if the static moves to the left speaker, it's your amp. If unchanged from the RIGHT speaker, there the problem lies.

If the static DOES move from the amp's IC cable crossing, it's your source/preamp.

Keep us posted...

Red Dawn is not sheilded, as speaker cables should not be anyway. What happened when you took out the cables you suspect as being faulty and dropped in something different, like a zip cord or anything else, or did I miss that you actually tried that?

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.
