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!

Cable elevators?
Pretty dang obvious...they elevate the sound, man. Plus, they look cool. 
What is the theoretical likelihood that anyone who's put a lot of time and money into a project will forever bind themselves to the projected end? And swear they hear the difference?

Why? Is that the way it works with you?
I have a quazi-high end system.   I experimented with cable lifters.  I found that 1/2 round vibrapod/rubber-like balls under the cables benefited the sound the most.  They eliminated vibration and elevated the cables 2" above the nylon carpeting (90oz-dense).  I tried caps on my unused terminals on a tube preamp but it diminished the sound quality in every location so I don't use them.

I found most of these expensive so made some myself but didn't like the result.  Judging from what is now available and the prices, I think many audiophiles may have lost interest.  I'm going to try them on my new system but found that jack pad adapters may work so ordered a few:
