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.

Yes some people have problems..
I have this year built a new upper floor on a new house (2012). (So new wires)
Have installed proper fuzes and so on.
My power amps is off grid and driven by a 12v car battery.
I use a passive preamp (do not need power)
Beside that the TT motor get power from the wall the RIAA preamp is the ONLY thing that in the signal chain that is connected to the wall/mains.

And of course I get all the clicks and pops when someone is turning off/on the lights or appliances somewhere in the house if they are on the same phase. As my system.

And a vinyl rig do not need additional clicks/pops!

So I am thinking of how to get the RIAA stage offline somehow.. (?).. But the PCB wants ±15v.

Hello,
I think it boils down to your cables and the resolution of the system. When I started getting into better components and cables I figured out the difference in recordings. 1/2 of my CD collection was from BMG. Horrible sounds came through my new system. Luckily I was able to trade all of my BMG for the regular/ better recordings since a friend owned a used cd store. I can’t even fathom listening to some of your systems in your properly treated rooms. It’s a double edge sword that’s worth it if you can afford it. If I can make it to Seattle someday I can finally listen to Michael’s record collection. He might make me clean some of his records for the right to do so. JK. Bottom line, If you raise or separate your cables like in MC’s picks and you hear the difference, do it. If it doesn’t move on to the next suggestion.

Optimize, Demo the Puritan power conditioner. It might help. Demo it first because they are not cheep but the do work without choking the sound.

@hshifi thanks for the tip.
Need to see what i could do abut it I am little bit of a DIY:er. But there is some other projects in the pipe.

Optimize,
a bipolar +- 15v battery supply is a relatively simple affair. It might get sticky adapting it to your circuit.
