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!

@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.
@drbarney1 ....I actually read your post in it's entirety.

Flawless logic....that's burnt my little brain entirely as well.

I will send you an invoice for the time it will take me to put all my little marbles back into my skull.

However, my results Will Vary....to degrees unknown at this time.

I spent $160,000 in building my custom engineered listening room.  My former $30,000 listening room which was not engineered but used some of my concepts (5.5" 3000 lb psi steel reinforced slab, 2X6 staggered studs on 8" plate every 8" dual 5/8" soundboard and 5/8" X drywall, 90 lb dense plush carpeting, separate subpanel, 20 amp breakers 12 g. wire, SR black power outlet) but had vaulted ceilings to 11.6', multipane wood casement windows to the sides of the speakers and 1/2 height rear wall, steel CD cabinets for 4,500 CDs, 18,000 LPs and 5,000 78s on the walls.   This room had many acoustical issues.  My professionally engineered room which I have detailed on other Agon posts is 100% better.  Sound is evenly distributed (with 25 Hz versus 32 Hz in former room) with NO bass humps or thumps, superior resolution, superior imaging, etc.  Today, in Enjoy the Music on-line, one writer documents that he would spend 40% of his audio dollars on the acoustics and 60% on the equipment, speakers and cables.   http://www.enjoythemusic.com/magazine/viewpoint/1020/Listening_Room_Acoustics.htm  I agree with him.  My system is about $70,000 retail; however, my anticipated new speakers will make it closer to $105,000.  Still, I have no worries about the acoustics.  All my music is now located in the adjacent room so I have a 100% truly listening room only environment.  Oh yes, those $50 in cable lifters come in handy for improving the sound if only by 5%.
