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!

To each his own experience and YMMV.  I was skeptical about cable elevators but decided what the hell give them a try . I have found they make a difference whether the cables are on wood floors or carpet. The benefit in my 2 systems was apparent right away . I'll +1 millercarbon on these statements he made.

" Greatly improve sound quality. I've done demo's. Its easy to hear "
" Improve clarity, detail, soundstage depth, and focus "
Easy enough to try for yourself. An option for you -  MusicDirect sells a few different elevators, you can select a version you want to try and if you don't hear a benefit in your system/room return them for a refund within their return period (cost to ship back is on you) . Likewise, they sell the caps so you can try them as well.



Make your own elevators out of cardboard. Take a listen. Please post results. 
Experimentation is (and always has been) the basis of scientific discovery.      It works in your listening room, as well (whatever the topic).       KUDOS, to those so disposed!

Used elevators, listened , no difference. 

Of course this gives no useful information unless it was done in a controlled listening test and the results were repeatable. 
See what I mean jcolespeedway, tons of hand waving but not a real technical discussion no matter the expanding number of posts.

One person likes to use the word science a lot but offers no confidence they have any significant background in the related science. One likes to talk about vibrating cables but likely has never done the very easy work of measuring the level of induced signal in a vibrating cable.


I do encourage you to try out cable elevators just get someone else to raise and lower your cables without telling you what they have done.
