So because of the weight of my Parasound amp, I had to move it down my chain.

All my audio cables are Belkin or Fosgate. They do their job - but they are also only 3 feet.

So I got into a situation where I needed about 3 1/2 feet between my Integra Processor and my Parasound Amps.

We'll, enter the good old, haven't used it in 10 years Monster Ultra Component video cables that's 8 foot.

So it is now connecting my LCR channels and you know what?

It sounds pretty good. I don't notice any difference between this and my audio cables. And it looks pretty damn sexy as well.

I can only load pictures about half the time on AVS these days so I cant see the sexyness, but if its working congratulations! I've been buying the Amazon choice cables lately and they seem to work great and are really cheap. Not all that sexy, but ugly things need love too!

Well count me in as an audio criminal too because that's what I use between my AVR and amp with my LCR; a component video cable. Works like a champ.

Did you actually expect a difference?

Honestly from an electrical standpoint you shouldn't be even slightly surprised. These cables are the exact same, except they may have better shielding because video has a higher bandwidth. Possibly even lower capacitance too as video cables often use foam dielectrics and such to lower capacitance.

I had a feeling but I never did it. It's like an unwritten rule - a cardinal sin if you break it.

And putting a component cable to connect between 2 pieces of $1000+ gear isn't exactly common.

So before I ordered 7 6 foot digital coax cables, some old component cables just worked.

The Monster Cable worked perfectly. It's color coded so the green wire went to center as indicated on my processor.

Literally any cable you can buy on the shelf with 2 RCA ends will work for audio. 50 ohm cable, 75 ohm cable, analog or digital, audio or video, it doesn't matter at audio frequencies. You can even use S/PDIF coax for analog audio with zero problems - though using analog audio cables for S/PDIF may or may not work since the cables aren't guaranteed to have a characteristic impedance that S/PDIF needs (analog audio doesn't need that).

Really wanna blow your mind? A coaxial digital RCA cable will work, too, lol!

But, really, this isn't a surprise -- the only difference is a component video (and coax digital) RCA cable just has to have a 75ohm impedance and, likely, will be better shielded. A decent RCA audio cable will likely be usable as component video or coax digital, too, but it's not guaranteed to have the proper impedance, so may not.

edit -- guess @DonoMan beat me to it, lol.

I'm using something from an older school: a composite video set. Red, white, and yellow. As far as I know, all 3 cables are identical coaxial ones. Yellow I use for the center.

Works perfectly, of course.

Nice.

First one that comes in and says they're using an s-video cable with home-made RCA adapters on each end is the winner.

Why would you expect a cable with a much higher freq requirement (video vs. audio) to perform worse?

There's a $3500 cable on USaudiomart that might interest you.

I'll never understand why people spend so much on cables.

Oh yea? I'm just gonna use a metal hanger now to connect my amp to my processor. Beat that!!! Lol

Ha!

Wasn't there some test done doing just that (using a coat hanger) and they couldn't hear a difference? Seems like I read about it on AVS but it was quite a few years ago.

While that might work for line level signals in some cases, it works better as speaker cable. When noise is induced into a cable, it is usually* (edit to add word usually) done so weakly, such that if you have a low impedance like a speaker, the noise will basically be shorted out to almost nothing (there isn't enough energy in the noise to really do much through an 8 or 4 ohm speaker). But when driving a high-impedance signal like the input to an amplifier, the noise is capable of changing the voltage more, because the signal is much lower power and is not able to "drown out" the noise so easily.

https://consumerist.com/2008/03/03/d...les/index.html is the link

Note that while the image at the top shows RCAs, the text says speaker wire.

Aluminum foil. Coat hanger wire is too stiff.

I've always used component video cables for my analog audio connections. Even for the 6/8 channel anolog audio ins/outs of the old universal dvd players. And right now excellent quality component video cables are dirt cheap. Why not use them?
