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

Michael

thanks for the advice, I will try today the various tests.

I began to notice the static on right speaker only after changing the speaker cables from nordost to audience so that is why I suspected the speaker cable (especially since au24 unshielded sppeaker cable).

I have already tried a different ic between preamp and amp and get same right channel static so I know the problem is not the ic going into the amp.

I have now tried a different speaker cable and switching the interconnect but still have the same problem.

The right speaker is not near a switched power supply.

I have tried slight changes in the routing of the right speaker cable without success.

Maybe the problem is that for the tv and video components I am using a monster video outlet strip and again the tv is closer to the right speaker than the left. However, none of the audio equipment goes into the monster video strip nor do the audio equipment go into the same wall outlet as the video equipment.

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.

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

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.

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
More to discover
