Has anyone who owns >$50 powercords ever wired a house? - Page 2

I wire my mains with shielded toslink cables.

optical power is the best.

lol

When house wiring is thicker than stock power cables, then thicker power cables could be better in theory.

Just in case someone brings up rewiring the house, please just get an electrician and don't risk electrocuting yourself.

First of all let me state that I do not use designer power cables - the most I have ever sprung for myself is the Iron Lung Jellyfish at $29 each. I have bought some used gear that came with more expensive power cables, but have never bought into the idea that this is a good place to spend money.

That said, I DID pay an electrician to run a dedicated 20 amp circuit from my panel to the hi-fi, and I promise you, that makes far more difference than any "audiophile" power cable ever will.

This is interesting, I've wired half my house but never considered doing this. I think I will add it to my to-do list.

I suspect, though I have yet to verify it, that the capacitance of expensive power cords is responsible for filtering out noise in some way. Or else some of them have noise filtering caps hidden in the plugs. I have had better luck so far with the single power...erm... conditioner or filter or whatever it is that I bought. I have it in mind to build a box with noise filtering caps myself though since it's cheap to do.

Well worth doing. Keeping other noise-polluting stuff off of the same circuit as your hi-fi really is beneficial.

i've installed 50A sub-panels in garages, multiple spurs in my house, for both isolating my hi-fi on a dedicated breaker, and other household electrical needs. i agree, a dedicated spur is a must. i did like the improvements that my DIYed VH-Audio PCs made when plugged into my dedicated spur. i would never spend more though. i'd rather save my money for Mundorfs .

It is a bit like a harbour wall. So what if there is a storm at sea, so long as the harbour is protected.
Now, I'm sure it's been posted elsewhere, but could you more thoroughly explain this "other way around" thing? It doesn't make sense to me when it's just stated like that. Damage has already been done by the house wiring, the power lines, the generator, what have you. So in my mind the power cable is a very small portion of the wiring.

Let's just say for simplicity that the wire to the generator does nothing. And let's also assume that so many feet of regular ol' wire degrades the quality of power by so much percent, say 1% for every ten feet. If your house is wired with 50ft of regular wire, and you have a $500 10ft power cable, then by the time the power gets to the cable it's at 95% of its quality. Unless the cable fixes that 5%, it's really only preventing more degradation. Degradation that's relatively small in comparison. And if a cable is meant to fix the signal, wouldn't a dedicated conditioner do better than that?

This is all assuming that a 5% decrease in power quality even matters much to the sound after it goes through a conversion to DC.

Some power cables might have high emf/rfi rejection so it is not perfectly accurate to say the damage is irreversibly done by house wiring. It's important for people to realize that house wiring is usually thicker than stock power cables. Stock power cables could possibly do more harm than the house wiring in certain scenarios (and assuming there's a difference in power cables), in which case it may be preferable to have power cables with more ideal characteristics, which may change according to different electronics.

yes we re-wired our whole house. simply because wires were really worn out(probably as old as the house which is >50) but, we were renovating the house anyway.

The stuff in your walls is solid core copper. Not the stranded garbage in a two dollar power cable. Cracks me up when people pretend like a freebie power cable is equal to the stuff in the walls.

Shielding on the power cord does not remove RF already present on the AC wiring. It just prevents further RF from entering along the cord, or RF from the power cord itself to be released into the surroundings.

What does suppress high frequency RFI on a cable are RFI chokes (snap-on ferrite core clamps) which are very inexpensive, and can be purchased separately and added to any power cord, if it doesn't have them already.

Technically speaking, the chokes are not part of the power cord itself; they are attachments/accesories specifically used for noise suppression. They do filter high frequencies in the order of MHz.

Funnily enough, some ridiculously expensive power cords don't have ferrite cores, and some don't have shielding.

Conductor geometry also has an effect on emi/rfi.

My perosnal opinion is that the psu or power conditioner should handle most of the emf/rfi, not some super well-designed power cable. When you consider the cost of some of these power cables, you might as well get an electrician to rewire your house for dedicated thick wiring with no connectors. And your audio gear better be up to snuff too.

Although running a dedicated power line to your system sounds extreme, it does seems to make sense for high-end systems.

For me, the only concern in power cables, is the same as in any other cable: Does the connector properly soldered/etc to the wire? This is the only reason why I won't mind paying a little extra for a hand-made cable. All other "mumbo-jumbo" is... well... maybe you should checkout the Sound Science forum.
