Shorten those lengthy power cords?

Hifitime, Good advise.
I was recently at Best Buy. I heard they have a little inexpensive coax speaker receiving great reviews and I wanted to check it out. I approached two sales people and asked where their hifi speakers are located in the store. They both looked at me with confused looks on their faces. Finally one of them ask me if hifi was a brand? I said no, I'm looking for hifi speakers, you know hifi stereo. They still didn't get it.
Anyway, it was refreshing to see your name with hifi in it.

For rolling your own, Virtual Dynamics has DIY cable fabrication instructions available on their website. There are several others as well, whose names I don't recall but no doubt someone else will chime in here.

Do not shorten electrical cords. It will hurt resale. And how many miles from the generator to your house. 2 or 3 more feet will have no effect in fact cutting it raises only problems. GIVE ME A BREAK!

The Bob Crump designed 'Asylum' DIY power cord is made with Belden 19364. I've used it for exactly the reason you describe, to make cables that reach my components without having a lot of unnecessary clutter to hide. The 19364 with Marinco plugs is very easy to put together, affordable and has worked very well for me.

If you go the DIY route, check out the Chris V website. There's a ton of info on what PC fits which application, how to measure, different recipes + all the parts.

For a basic power cord, I suggest getting some 12/3 Carol cable at Home Depot & some inexpensive ends at Parts Express. This recipe makes a decent cable.

Just make sure you wire them correctly to keep them in phase. The little GB elecrical outlet tester works fine & Lowes sells them. The IEC to AC adapter can be found here
