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!

AG just censored my word a—. As in 'kick a—' amplifier.
Clean it up, Katzenjammers!
Hi definition light bulbs. Now there’s an idea. I saw an LED bulb on Amazon that had a bluetooth speaker in it!  Go for it!
Let me get this right. So now we can’t hear any of the noise created by our gear, wires, home circuitry, carpets or jittery sources when we play music loudly? That’s when we hear it the most! If the S/N ratio is 60db (below normal conversation) you can’t hear it? Yeah, that’s about as sophisticated as we thought back in 1975 when an AR turntable seemed quiet.
Is this supposed to be a zero-sum game where you either hear it or you don’t?
Noise is not a separate track to be measured and heard at the same time as the desired signal. The noise is part of the signal riding in its entrails like the Coronavirus, infecting and inflaming and generally causing mayhem to our systems.

My doc says my sore shoulder should respond to anti-inflammatories, so I take one . . . and I massage the sucker . . . and I apply heat . . . and I exercise it . . . and I do anything I can to relieve the inflammation regardless of whether or not I can identify the aspirin, heat, or massage as affecting a particular muscle. It’s better!
Apply some anti-inflammatories to your system and then turn it up and enjoy what you have wrought.

Skepticism is the opiate of the closet misanthropist—who expresses his derision for others’ findings/opinions by claiming his own are based upon ‘science’ but then refusing to provide the numbers proving cable elevators to be snake oil.
