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!

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.
tuberculin,

I use silicon (I think they are silicon) covers for pretty much anything I could find them for. No dust enymore. Of course, the question is why should I care about dust in the connectors I am not using. It just makes me feel good knowing things are clean.

I never bothered to check what happened to the sound. If anything,
@djones  I tried taping my speaker cables 5' high to the rear wood wall.  The result was brighter and thinner sound.  Yuk!   I tested various cable lifters and no lifters.  There were marked differences, between 3% and 10% difference estimated.   I preferred the low cost half vibration dampening half "rubber" balls.  It's as if there was no effect, certainly not negative and about 5% better than cables lying on the very thick, dense nylon carpet.  Not monumental, but appreciable difference for maybe $50.
Stay tuned--I am interviewing some electrons next week and will discuss this with them.

Look, if YOU hear a difference, it is there. If YOU do not hear a difference, why worry about something this silly?

Last I checked, it is all about the music. I promise you that YOUR ROOM is a million times more important for what you hear than some stray electrons, which, I might add, fill the atmosphere along with alpha, beta, and gamma rays, among tons of other stuff.

Work on finding the best possible room modifications and forget all the cable stupidity. It is, was, and always will be bull regardless of all the oscilloscopes in the world. Oh, probably stay away from 28 gauge Radio Shack wires for speakers. It is ugly.
