But one thing you mentioned would really help. If I shut off everything in my house.. except the line to my audio system.. would that be comparable to getting a dedicated line?

Here's what is going on, as best I can understand it. Which is way better than most. No one else here even comes close to having done as much or as many different things to improve power to their system. Challenge! This is only the tip of the iceberg https://systems.audiogon.com/systems/8367 Every wire is an antenna. Electromagnetic radiation of every kind crosses every wire inducing a signal in that wire. That's the improvement you hear flipping off the breakers, it reduces RFI by cutting off a whole slew of antennas. This is separate from back EMF noise in the line from devices that are connected and running. Those two things together are only part of the problem. Another probably even bigger one is transmission efficiency. Our systems do not draw power in a smooth even flow. Its extremely uneven and varies constantly with the music. Just how much this matters is very easily demonstrated by something as simple as swapping out diodes or caps in the power supply. Every little connection along the way is a gap the power has to bridge on its way to your system. You think its a solid connection. You think there's no gap. On a microscopic level its craggy as the moon. You think the power flows. On a microscopic level electrons are piling up until there's enough and then zap they jump across the gap. Marketing people call this micro-arcing. Audiophiles just love marketing lingo. You are well on your way to wasting a phenomenal amount of time chasing marketing lingo, measuring and all of that. Monumentally huge waste of time. This is why I say to relax. You're all worked up thinking there's something there you can search around and find the answer to. Well there is, and there isn't. There isn't in the sense you cannot find any one thing to point at and say do that and done. There is in the sense you can say its all crap and so anything and everything I can do to make it better is a step in the right direction. Just know its like taking a step here on Earth. You can walk your whole life and never run out of steps. Round and round. Enjoy your walk. Its endless. |
There are ways to visualize AC line noise, with a newer (FFT feature equipped) O-scope. The correct Spectrum Analyzer can come in handy, as well. ie: https://www.testandmeasurementtips.com/measure-powerline-quality-oscilloscope/ Of course; familiarity with and access to the equipment is a prerequisite. I’ve mentioned this much easier method, on these pages, before: http://www.gryphon-inc.com/Spec%20Sheets/Power%20Monitoring/917010A%20-%20ONEView.pdf |
Not nearly as discerning, but- there’s this type of, "sniffer": https://www.amazon.com/Digital-Display-Tester-Measuring-Instrument/dp/B082M1BBG3 |
