Wrapping power cords and interconnects with copper foil.


Ok..not sure other people have done what I tried recently but I’ve found a night and day difference in sound quality after I wrapped my tube power amp power cord (rogue Zeus) and my cheap audio quest interconnect cables with copper foil. I even wrapped by phono cable coming out of my turntable to phono pre-amp. The detail retrieval and pin drop silence after doing this has made by jaw drop. Cost was $40 worth of foil wrap. What do you audiophiles think? Have I changed the sound signature in a negative way somehow?

There's some humor involved  in all of this. In the audio world, nothing new there, but I was unaware of the theory that shielding interconnects was disadvantageous due to inductive effects.  How does that work?  You wouldn't expect interconnects to radiate much energy, true, but shielding power cords makes a lot of sense. But wouldn't your interconnects need protection from the power cords?  Or would they already be ok if you were using good power cords?  Even worse, could you get I’m away & unavailable :) with el cheapo power cords by simply foil-wrapping them?  People are spending thousands of dollars for those things, maybe not needed if you can wrap a stock thick Belden cable with foil?  Maybe @tubelvr1 should have left his wrap job on just the power cables and it was overkill to do the interconnects. 

Can’t say I have seen, ever used, unshielded phono interconnects from the TT to the phono preamp.

@carlsbad2 no didn’t ground it, just wrapped it with self adhesive foil. Seems to work wonders.

It doesn’t need to be grounded to work as a shield, Faraday Cage. You might want to experiment, then listen for any differences.

You may find ungrounded sounds better. Especially on the AC power cord. It really depends on the equipment the power cord is feeding.

Just like to point out that, weight for weight, aluminium is a better conductor than copper.  Copper usually weathers to a green colour - verdigris.

Consider whether the RFI carried by power cords is actually generated by the components they power, not by the wall supply!  Much more plausible ...
