marce Posted October 1, 2019 Share Posted October 1, 2019 I would probably test cables etc. like they do for Cern, LIGO, Avionics, space stuff and most other installations involving electronics... As they are a conduit for a signal from one place to another, the perfect interconnect having no parasitic effect on the signal, this of course is impossible, so you have to determine how much effect a particular cable is having... Cables should have as much effect as the led on your remote control.... Link to comment

When you say the equipment is on hand, is it new to you or have you been using it for awhile? If I assume the equipment is brand new and new to you, I'd definitely start out with the stock power cables, and use some straight forward interconnects and speaker cables using Mogami, Belden or Canare wire. A year from now after you have broken in the equipment and adjusted things you will be in a much better position to evaluate cabling. I believe cables make a difference, but it is a minor effect as compared to break in and speaker positioning. If you do not already have a copy, you'd be money ahead buying Jim Smith's book, "Get Better Sound". What a load of twaddle, of course wiring matters, I'm talking about wiring for something like CERN or LIGO or a space craft or a nuclear power house or pro audio or a million other things where wiring is critical, its the audiophile magik wiring I disagree with.

Reading my original post, I realize this is my fault. I know enough to understand that the cable debate is heated and very subjective. I understand that no one can tell me what is "best" for me or my system. 10-4. Got it. I think what I *meant* to ask was this... What is the best way to test system quietness? Is it as easy as hitting "pause" on a source and then cranking all gain adjustments to the maximum setting? Would this allow me to amplify any noise in the system and possibly measure it with a decibel meter? Seems like a potentially interesting experiment, but I wanted to ask before I did this. That's it. I will now duck under my desk and await your replies! 😬 Proper noise measurement is a pain and would involve an big Faraday cage (EMC lab), not doable for most of us... A scope of multi meter may give some indication of noise on signals... again without isolation its hard to locate the source.... Link to comment

A set of measurements, or how the measurements translate into the sound quality of what you hear? For most audio fans, its likely the latter. Power cables seem to take time to settle in and reach their ultimate performance so this is how I go about comparing cables (as opposed to 'testing' cables). If you want to combat noise in a system then you have to understand the noise, that means measuring it. As to power cables if you believe they can change the sound they will.

marce Posted October 6, 2019 Share Posted October 6, 2019 Don't forget the importance of a 25/20mm fuse as well! Pass Labs supply power leads that will supply the required current and are safe... https://www.stereophile.com/content/nelson-pass-seminar-cas6 Link to comment
