Dedicated Circuit wire alternatives?


Hey. I've been through the archives and found that the general concensus is that Belden 83803 is the wire of choice for dedicated circuits. At $2 a foot it's pretty pricey considering I would need 100 feet for just my amplifier line.

1) Does the analog/digital line need to be 12 gauge or can I use 14 gauge 83753?

2) Are there any cheaper alternatives (other brands maybe) that offer the same noise rejection traits for less momey? Romex doesn't seem to work as my equipment is the only thing plugged in to it's current line and I can hear the effects of the refridgerator turning on.

Thanks!

Sounds like you have a bad capacitor in your fridge or it is on the same phase as the stereo and it should be on the other phase.....Go with 10ga Romex and use all that inductance as a filter and run separate lines for digital and analog making sure the phase is the same as well as on the opposite phase from the appliances....
Tinned conductors typically tend to lend a very "edgy" sound to the upper midrange, i.e. this is what is used in many "ribbon" cables in SS gear. Replacing the "ribbon cables" in many SS components with better quality copper wire gets rid of the "SS glare" that so many folks complain about.

With that in mind and since so many people appear to hear the effect of power cords on their systems, i would think that the tinned copper conductors of the aforementioned Belden would be a BAD thing. I am STRICTLY guessing here though as i have no first hand experience with it.

I agree with Albert and Bob and suggest using good basic wiring, running a dedicated ground and having it all installed in a shielded carrier ( conduit, aluminum flex tubing, etc... ). As mentioned, pay attention to which phase or leg of the breaker / fuse box that you're tieing into. Run seperate lines for the amp, analogue components, digital components, etc... The heavier the wire, the better. This is especially true for the amplification circuit with the others being less critical due to less current draw. Sean

How do I wire my new lines out of phase? Albert, I don't understand what you mean about lifting the ground within the Romex? How would I run a separate ground then?

Please excuse me if these questions are dumb (or scare you). I spent two years as an EE/CE major and regularly work on my car's DC system but I have no practical experience with house wiring (being that this is my first house).

Rcrump, I definitely have a bad something or other in the fridge. Until I replace it, it will provide a good benchmark for the power line changes to my audio gear.

Thanks!
Sean, you do have first hand experience with tin plated conductors in power cords....You also have a ton of first hand experience with tin plated copper conductors used on virtually every individual component as well as boards in your gear.....Tin ain't bright.....
Leoturetsky, I should have made that more clear in my post.

With a dedicated ground attached to your wall outlet (the ground screw) and running to a dedicated ground rod, the "original" ground wire within the Romex becomes useless.

By simply clipping it back BUT attaching the other end to the breaker panel, you get a little additional benefit.
