A Couple Little Things I'm Wondering About


Two quick questions for anyone with any experience with either topic.

1. Why do some folks with usually higher end systems use those cable lifters to keep the cable elevated? What are they intended to do? If you use them, what do they do for you please? And if you know do they make sense from a purely technical standpoint? 

2. I bought a bunch of those gold plated caps to cover all the unused RCA jacks on the back of my AVR. I believe they are intended to keep noise down. If you use these, please comment on them. Do you think they do what they're supposed to do, and/or do they make sense from a purely technical standpoint?

Thanks!

It depends:

how capacitive is your floor ?

does your electronic short to ground inputs not selected ?
Anything on which your cables rest can add it’s constants to their dielectrics.    That changes the permittivity and permeability.      If you’ve spent money in an attempt at bettering your reproduction, on good cables; you’ve detuned them (ie: resting on wool, synthetic fibers, etc).       The Naysayer Doctrine preachers may scoff, because of their 1800’s belief system, but- 20th Century science says that the electromagnetic current/signal travels outside the conductor ("waveguide") and through the dielectric.     Even wiki-scientists are aware:        https://en.wikipedia.org/wiki/Speed_of_electricity#:~:text=Speed%20of%20electromagnetic%20waves%20in....                                                Just one possibility, regarding cable lifters.
