Romex to your amp?


One of my good friends, a non-aphile, asked me an interesting question...
I was discussing with him why my new pc made a nice improvement in my SQ.
So he asked me this question:
Why not take the Romex all the way from the wall and connect it to the amp...instead of
using an after market pc? His logic was that the in-wall cable is Romex and therefore a straight run to the power amp would be better ( or at least as good) as a break at the wall plug and an after market pc to the amp. Does he have a point??

Is your house wired with 5 nines copper from your private generator? You do know you have 50+ feet of Romex in your walls behind your stereo.
The trick to power cords is they filter out some of the high frequency interference. Its not that the 3 foot cord of some ultraconductive big gauge wire amplifies the voltage you lost going thru the first 50 ft of Romex. You can get 95% of the way there just by twisting the positive and neutral AC leads tightly and have a loosely wound wire that connects to ground that acts as a shield. Then add some plugs that are better than the cheap injected molded nickle plated crap.
For my DIY power cable I decided against using Romex. I was seriously thinking about it but the stiffness mentioned stopped me. I tend to play around with my system too much and did consider the solid wires being brittle. But if you just plug things in and stop messing with it will be OK. Its more about the design and the way you plug your components in. Ended up going with some 12 ga silver plated Teflon jacketed mil spec wire instead and some pure copper Sonarquest plugs . It works.

My response:
03-15-2002 6:36pm "If you want to get extreme, hard wire your mains to whatever uses them. For example, cut off the male connector of what usually plugs into the wall and solder the wires directly to the leads coming out of the wall (have a pro electrician do this of course). Doing this to an amp is the most logical application (could be risky due to electrical storms, power surges, etc. unless you trip the breaker when not in use). Sounds like you’d get the last drop of juice this way!"

Like I mentioned its not all about the juice. The resistance loss of an additional 6 foot piece of wire of any reasonable gauge and a few plugs is not as important as filtering out the RFA interference.

But........If you would take apart the last 6 feet of Romex, braid the leads like I described, then solder it to your equipment. You would definitely be on to something!
Didn't necessarily mean "electric" juice. Meant "juicy slurpy goodness" juice. BTW, this was seventeen years ago.
I was going to do exactly as your friend described except wire the Romex into my Shuyata Denali Hydra 6000S power conditioner instead of an amp. The Shuyata Denali was intended to tale out any line interference.

Unfortunately, I was informed this was a NEC (National Electric Code) violation which might void your homeowners insurance if discovered after a fire for example. Other than that it is logical it would work if your power conditioner would take out any RF or other types of interference, rather than a ridiculously expensive power cord. Just a thought, not based on anything but common sense, admittedly not expertise.
