I recently completed outfitting my system with Pangea AC-14 power cords. I had a Wywires cord on my preamp and bought Pangea's from Audio Advisor for $30 a meter when I had the extra  cash and now have them on all my gear. It really makes a difference, I was not a believer until I heard the change last year so I slowly over time changed them out.
  Clean, black background...nice dynamics....a cheap and cheerful way to move your sound up the ladder........ :dance: :dance: :dance: :dance: :dance:

I figured my power cords need be able to draw as much current as they want for my active speakers so I bought a pair of Pangea 7 gauge cords.  Seems like things are more relaxed.

Yes power cords do make a big difference in SQ over stock OEM cords that come with the equipment.  I don't really hear a significant difference between different aftermarket cords, albeit I've never had any uber expensive ones in my system, so advocating cheap and cheerful in power cords seems like a sensible recommendation.

I don't know why PC's should make such a marked difference, but they do.  I've heard it proposed that the major difference is the plugs, eliminating vibration and poor connections makes the biggest difference, and you can get most of the benefits by just replacing the plugs on your stock cords.  This passes the smell test for me, as how much could heavy gauge shielded wire differ?  I'm ashamed that I haven't got around to testing this out, as I've always had enough aftermarket PC's to fill up my system.  However the addition of a new DAC has left me one short, so I should be testing this soon.  Or maybe I'll wimp out again and just buy one, I like the deals you get on Zu Cables on eBay, definitely C&C prices.  I also keep looking at Ed's suggestion of Pangea's from AA, they look very professionally made.

Good thread Ed, I'd like to hear more C&C suggestions on this, DIY recipes might be good as well, James R sent me one, I'll see if I can find it.  And anyone with theories on why a friggin power cord should make such a difference are also welcome, understanding the psycho-acoustic audiofool argument has been made ad infinitum.  However I have sympathy for the argument that there is no sound engineering reason why something not in the signal path sufficiently designed to deliver a specified current and voltage and to reject normal levels of RFI/EMI should not sound the same as an audiophile PC cable.

Hospital Grade Power Cords are inexpensive and are high quality....

If a life depends on them, I'm sure my stereo will live!

And wasn't one of these sold as a Jellyfish PC or some such thing?

Ah, yes, here http://www.audiocircle.com/index.php?topic=77657.0  The consensus was the hospital grade at $6 from something like Jim's link was identical. 

How these compare against different price levels of PC's up to $500, but mostly C&C examples, is here http://www.head-fi.org/t/219202/its-done-power-cord-shoot-out-22-power-cords-reviewed  The hospital grade cord was given a favorable, if not glowing, review by the poster.

The Pangea cords are an excellent bargain. Not up to the sound of more expensive cords but it's definitely a case of diminishing returns relative to the respective prices.

I think a significant difference in the sound between stock cords, which usually have nickel plated connectors, and aftermarket cords (at least of the same copper gauge), are the (usually) gold plated copper connectors on the latter. They give a more realistic tonality.

Un-plated copper, as used by Kaplan Cables and Triode Wire Labs, sounds even more natural to me.

The rhodium plated connectors sometimes found on more expensive cords sound horrible to me: forward, with a glaze over the music.

The best of both worlds is to use the Hospital Grade Cord Plugs and use DIY wire.   I used both pure silver and copper braided together....sounds good in my system.

That's what I have in my head to do, but lack the motivation.

Good recs so far, but also make sure you are buying connectors WITHOUT nickle plating. I have gone with the entry level Wattgate IEC and male plug and they are a good value IMO. $13 for the male plug and $20 for the IEC, no nickle, very easy to use and they are cryo treated.

Also, just found these receptacles, they are for MRI rooms, so they have no magnetic parts.... well worth the effort to install.

I had an idea for a power cord based on designs by Kimber and Shunyata using a run of Kimber 4VS and 8VS speaker cables.

I basically expanded the 8VS braid so I could slide the 4VS cable through the center. 

4VS (all 8 wires) = ground
8VS (8-Hot, 8-Neutral)

9awg for each leg.

I got the cheap WattGate AC and IEC connectors.

Total cost= $140

Works well!

Using not for 120Volt Ac wire for powercords is BAD, very bad.
The insulation on Kimber speaker calbe is NOT RATED to carry 120volts.
Both for your own safety, and for your insurance killer if it starts a fire, using speaker wire for power cords is BAD.
Sorry to be a bummer, but  a powercord made from ANY speaker wire iss a terrible idea,anddangerous.
Unless that wire is specifically insulated to be able to be used for 120 volts use.

Actually I confirmed with Kimber the voltage ratings and the VS cables are rated for 400 volts.  Their TC wire is even higher and has a more durable insulation.  The braided ground may be overkill but I wanted to be consistent.
Apparently my idea isn't new as Russ Andrews sells the TC version of these over in the UK.

You can't plate gold onto copper. It will not stick. Copper has to be first plated with nickle, then plated with the gold.

I'm not surprised.  DH Labs is the same thing....

Should we be surprised that the reviewer picked the most expensive as "the best?" Through headphones no less.  :roll:

For over 15 years, Molecu Wire has plated gold directly onto 0.004 inch diameter OFC copper wire for the computer industry.

This wire is used to connect the read / write head to a terminal strip attached onto the suspension arm in a hard disk drive.

Billions of feet have been used in this application.

No nickel underplate was ever applied!

IBM was our first customer...and was our last until just some months ago...these discrete wires are now replaced by high density flex circuitry.

Yes, the nickel inhibits diffusion. Yes, nickel underplate is SOP for connectors, pins, etc.

Yet - no one has yet to tell me why no nickel was necessary for this hard disk drive application...esp. since this wire is the "first" wire to be seen by any data coming into the computer from the data storage device media!...a rather critical place, I would say.

Regarding diffusion time - it is my understanding that, at room temperature plus, detrimental effects due to diffusion would occur in a period of time which exceeded the product lifetime.

  I never knew that about plating, either way.
 I would do the diy interconnects maybe but as far as power goes I'm buying from a place that knows what they are doing, that's just me and my paranoia.
 Plus I have like zero motivation to do too much diy with my hands like they are with the neuropathy. As an aside mine got 50 times better from playing video games and having to manipulate a controller if anyone runs into the same issue.
 
  So do we know why in laymans  terms the power cord effects sound like myself and others hear?
 I was shocked at the difference I heard the first time I swapped a nice one in place.

There are a few cheap and cheerful surprises to have :)

... Iron Lung Jellyfish is hardly a PC to hang your system around ...

I would not be surprised if the triode PC would rise to the top ...
