A certain online retailer asked me for a review of Pangea power cords..

Power cables are a pursuit with binary results. If you previously had the el-cheapo 79 cent receptacle and 18AWG cord to your amps, they probably had significant I*R voltage drop when the amps called for more current during peaks. The law of diminishing returns applies here especially.

All you need to do is upgrade your receptacles to spec-grade or heavy duty at a minimum, and screw-wire them to your romex. The back-stab connections are notorious for making a very poor connection. Don’t forget to pigtail all of the other upstream connections in the branch circuit.

Similarly with the power cords on your amplifiers. If they are less than 14AWG, they are a weak link in the chain. You don’t need anything more than garden variety SJT extension cord wire that is sold at Home Depot and other home centres. 60Hz (or 110Hz or 400Hz for that matter) alternating current is not affected even remotely by the skin effect. Once inside your amplifiers, the path to optimize is through the power switch, which is often a weak point, and the rectifier diodes can be upgraded with ones that have faster switching and lower forward voltage drop, to make the filtering and regulation circuitry more effective.

These upgrades are all south of $5 each, and will strengthen the power delivery to your amplifiers much more than any $300 rhodium plated silver power cord could ever hope to.

Yes the alternate reality side of wires needs to be heard.
As is usually added into ANY high end wire discussion, and sleepwalker65 stepped up the the plate... To offer the alternate reality version of powercord heaven. I wonder if the high end wire fanatics bust in on all sorts of ’wire is wire’ threads? are there even any such animal? (I have never seen one???) or do only discussions of actual users of high(er than cheap) wire and power products ’get’ the influx of such wondrous homilies about how great ordinary wire can be??? I am surprised though sleepwalker decided to pop in on this thread about CHEAP as dirt powercords?? Maybe I missed his post where I discussed repeatedly and in depth about adding $5000 retail worth of Duplex and plugs on a whim??? I bet he saw those.. since why else add in the "" All you need to do is upgrade your receptacles to spec-grade or heavy duty at a minimum, and screw-wire them to your romex.

I wonder if that is really a metaphor???
What a nice guy to be sooooo helpful.
So you think he is telling me? or some other person who might get the notion to buy some fancy cords???
Kind of like the old hippie Hari Krishna a the airports, never know when he might find a convert.
Then I wonder do they think anyone is going to listen? Or are they just flapping their gums in the breeze for the hell of it. Guys like that MUST think their ’message’ has meaning and is ’reaching the masses’ gaining ground with every post... ??? Not in my Universe LOL

I think power cords, power conditioners, power outlets are going to become more and more important. Wall current is deteriorating, digital interference is getting worse by the day.
I cannot verify it because I have an integrated amp but most people reported that right power cord on preamp made the biggest difference. I can only say that it made big difference with integrated, bigger than with phono stage and bigger than from the wall to PS Audio regenerator. But that's in my case, experimenting with only four power cords. Best cord was best with everything as far as I could tell, Purist Dominus Rev B ferox. Good power cord should not make anything worse, and I don't try to 'tune' the system with cords.

Thank You for the review. Are you using both Kimber Kable and Pangea cabling/cords in your system?  Happy Listening!

Almost all Pangea, plus two home made cords with Furutech '28' Rhodium plugs. The IC mainly are Kimber KS1116 (XLR) and KS1016 (RCA)
With a few Cardas Pasec in lesser positions. Speaker cable Kimber 8TC, with a 1" cotton core.
