I have been a stickler about keeping power cables away from signal cables...on equipment ?


What I am finding very interesting, and to some extent, disturbing, is how close the power IEC inlet or power cable, is designed so close to the speaker or input / output terminals of amplifiers / gear. Many of my Hafler, Bryston and Citation amplifiers had / have this arrangement, and many of these newer and smaller chassis class d amplifiers have this arrangement. I have actually rewired ( or had rewired by a tech ) a different path separating the power line to the audio line within the chassis, and hearing a cleaner background when listening to music through these products afterwards. I am finding this to be the case, looking at photos of some other gear as well. I also believe, power switches and it's wiring, should be designed at the rear of a component, for the reduction of ac related noise, even though it might be an inconvenience with it's daily operation. Just as an aside.....I keep my gear on 24 / 7, unless I am on an out of town trip. Your thought ? Enjoy, be well and stay safe. Always, MrD.

The back of my system is a mess of cabling, but they've never given me reason to be concerned. 

I also use a variety of different interconnects but it's the IXOS ones I particularly dislike for their (pre-ghost encounter) Scrooge-like nature. Extremely thick and tight.

I'm putting my trust in the ability of the various manufacturers to have provided decent shielding on each one. They certainly look thick enough.

I have noticed that my current TV antenna cable (co-ax) seems to have more shielding than in previous times, an extra layer of tin foil if I remember correctly.

Does it make a difference?  Not as far as I can tell.

The only cable that does worry me is the one bringing in the internet from the telephone socket. It looks extremely thin and I can't see how it could have much shielding. Still it's the one that came with the router.

Nevertheless when I once changed it for something more substantial (highly rated on Amazon) I found that my internet speeds dropped noticeably. I put that down to the upgraded cable having more individual wires inside than might be good for it.

Things didn't change overnight so it was back to the manufacturer supplied thin grey cable and the usual speeds (16-17Mbps) returned.

For some reason, I guess just for peace of mind, or just in case, I do keep it as far as I possibly can from the a/c power cable (another very thin one).
