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!

I was wondering what direction your next change of topic would take.      The twists and turns are usually endless (circular thinking).     Those of your ilk are great at semantic gymnastics.      The term, "PULSE", in regards to FFT transfers, is now your problem?      (https://apps.dtic.mil/dtic/tr/fulltext/u2/a369180.pdf)      and: (https://dsp.stackexchange.com/questions/62176/difference-between-fourier-transform-and-fft-of-rectan... )                   "Convolution function" is the perfect description, for your cult’s program!      Nothing what-so-ever, to do with this thread and- no surprises!     So tedious!

I explained how my TacT’s program uses FFT to time/phase align my system, as simply as possible, and I’m trying, "...to look like an expert..."?      Hilarious!      Semantic Gymnastics is NOT a science, but- obviously all you’ve got.    Nothing you've injected here has anything to do with the OP's queries.       What you’ve proven: you’re a waste of keystrokes.      The ubiquitous last word is yours, with my compliments.      You obviously can’t refrain.

glupson,
I used them on a C-J PV6 and I did not notice a difference. My current pre-amp is relay controlled shunting the open inputs so I don’t need them.
