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.

Jeff Smith from Silversmith Audio offered this on another discussion group concerning his Fidelium ribbon speaker cables: he said to wrap them around power cord and hook them up to your speakers and see if you can hear ANY noise without running a source signal through it. He says you will not and therefor the proximity of his cables and power cords do not matter.

Brilliant. A dazzling display of logic! What I love about this is we can now also forget about not only noise but distortion. Because hook a cable up and run no signal through it, there’s no intermodulation distortion! No signal, no noise! Wala! Also no total harmonic distortion! This guys a freaking genius! All we have to do to remove noise from our systems is not run music through them~!

Sorry, but anyone thinks this Jeff Smith idea deserves anything more than ridicule, step right up. Defend away. Its garbage. (Also known as marketing, shilling, etc. Because he's talking about "his" cables. As if his and only his are able to defy the laws of physics. Dream on.)

My Herron VTPH2A power switch is on the back right corner, right next to the iec. It is a bit of a hassle. But for all the right reasons.

All my components have, and as far as I know have had, the power coming in on one side and as far from inputs as possible. Especially critical in sensitive components like phono stages. Now this may well be due to the way all my components are selected on the basis of sound quality performance, and sound quality performance alone. I do not care for specs nor do I decide based on technical stuff like what parts are used or how they are laid out. Because while all these things are important, no one knows enough to know which is most important, or how doing one thing one way matters more than another way.  

All I know for sure is all the best stuff (as arbitrarily decided by me anyway) is built the way you describe. This is also a big factor in why receivers are the crappiest worst sounding components in all of audio- too much stuff crammed too close together. Never a good idea.

My system looks a mess but is laid out with a lot of spacing between cables, including keeping them all up off the floor. https://systems.audiogon.com/systems/8367 And yes these details do make a difference you can hear.
