Monstrous power cables


I’m sitting in my listening chair looking at the over $1K power cable that came with my Running Springs Audio Maxim power conditioner.  The guy I bought the unit from said he auditioned three cables all costing over a grand and liked these the best.

The cables are about the diameter of the cardboard center of paper towels (maybe even thicker) and weighs about five pounds.  It’s absolutely monstrous!  I’ve got a piece of wood supporting it under the receptacle and use other items to support it under the Maxim.

The electricity is carried through my house probably using 14 gauge wire.  What’s the logic using more than that going from the outlet to any component?

I’ve got quite a few power cables of various diameters, the thickest (other than the one connected to the Maxim) being the AC9 s from Pangea.  And to be honest, I don’t think I’ve ever AB’d power cables, having just assumed they do make (at least) some difference.




Power cords, interconnects, and speaker cables are all there to serve you and your system.  If they are so bulky or heavy as to be a pain in the ass to handle, or risk damaging your equipment, swap them out for something more manageable.  Plenty of options, and rarely only a single type to achieve your sonic goals.


thanks for posting this, at a minimum it‘ll force lurking luddites (aka the usual suspects) into a bit of scientific thinking

Having read the link above…written by a chap selling very expensive extension cords, I see statements like this one: The current itself cannot be contaminated . Instead he refers to effects of EMI that exist throughout the power grid.

What I struggle with is that the power cord is not in the data chain. It simply feeds electricity from the wall, or conditioner to the power supply of any given component. And this, after it has run through hundreds/thousands of feet of cheap wire. I certainly agree that interconnects have a voice as they are carrying (especially analogue) data that may be audibly flavored.

Much is written by those with golden ears and expertise far beyond we mortals. But I can simply detect no difference whatsoever…granted that such nuance is subjective. Is there measurable data that verifies exactly what information is lost or flavored in the audio chain by the type of wire in the last few feet of electricity entering the transformers?

This is just my opinion, of course. Clearly, many here with hearing capabilities far beyond mine seem to feel strongly otherwise. The good news is that I can save the $$$ others may spend on a massive extension cord and plow it into equipment that my ears can appreciate. No need for argument, insult or debate. To each his own. 

I take a middle road, and if you read between the lines of some of the more learned opinions here, they seem to lean that way too.  

In my opinion (that is the term most recommendations here should start with, however, much more commonly I see "without a doubt") it is indeed size that matters.  Amps need fast access to power for dynamics.  Don't throttle the power with a light cord.

I use generic 10 awg power cords.  I do take the ends off of them and verify they have been well terminated.  If you don't feel comfortable with doing that and want something absolutely reliable, then spend 10x as much and get a $500 power cord.  Make sure it is heavy gauge, at least 12 awg, preferably 10.  I recently bought an amp with a 2 year wait list. I was very lucky to buy it before someone else did. the seller included the upgraded power cord he had purchased.  It was a $300 cord.  I looked it up and it was 17 awg.  I feel certain the cord is why he was unhappy with the amp.  I used it on my CD transport.

Like others here say, cords are not tone control.  Once you get plenty of power to your amp, anything else you hear is likely affirmation bias.


They can act like a “device” instead of a simple cheap 14-10g cord.

Super heavy gauge will certainly increase capacitance. You can also increase or reduce resistance. What’s the big issue here?
you can change these things inside the case (amp/preamp whatever component) as well.

I suppose it’s when to start calling them devices instead of cords??
