Power Cords - Just Say Yes


I'm the biggest cable skeptic on the planet. I've never been able to tell the difference between one speaker cable over the other. I've never a/b tested because I just can't handle that sort of thing when all I want to do is listen to music. The power cord however is a whole different beast. I know. I just replaced a 18/3 that was powering my Rogue Cronus Magnum for two years with an Audioquest NRG4. I know some people aren't fans of AQ but that's what my local guy sells and I support him 100%. He sold me a broken in demo which is exactly what I wanted. I didn't do an a/b test and I didn't have to. I pulled the old one out and tossed it in the copper recycling pile and replaced it with the AQ. I fired up my amp this morning and let her warm up. I pulled out Sylvain Luc & Bireli Agrene's 'Duet' and hit the play button on the remote. Right off the bat I had to blink my eyes to make sure I was actually in my house. Everything tightened up with a dead silent background. I feel like a fool for waiting so long to come around on this one. I'm still skeptical of whether or not I will notice a difference when I replace the power cord to my CDP, but if you tell me I'll notice I might believe you. Either way, that's my next investment.

My first "upgraded" power cords were homebrew.

I had a pair of Quad 63.

The power cords that came stock with the speakers were very thin wire,thinner than lampcord.

I used some solid core romex house wiring and soldered it to a cheap IEC, for the other end I used a cheap 3 prong recptacle.

In those days I had no dedicated lines and no power conditioning, but it was easy to hear the improvement the DIY power cords made.

So much so, that the chap who purchased my Quads asked if he could buy the DIY power cords after hearing the speakers .

DIY is a great way to solve the power cord debate.
Experimenting with better quality connectors and wire is the only way to understand that such things do make a difference,doing nothing will never answer the question for you.I like the Furutech connectors and have upgraded a few of my power cords with them.
I've also made a very decent power cord with their top tier power cord wire and connectors.But this was getting into name brand power cord pricing especially if you are looking at used power cords.

It should be obvious that if you hear improvemnts going the DIY route,you should then seek out some of the pricier stuff and compare.

You may or may not be pleasantly surprised.
Power cords can make more or less of a difference depending on the component power supply build quality and how much current it draws.
I would have to disagree with Rx8man.

I've upgraded the power cords on the power supplies of a Rega P9 and an SME 10 and heard the improvement the upgrade power cords made.

I don't think either power supply is underbuilt, but certainly isn't as demanding as an amplifier's power supply.
So I wouldn't be in too big a rush to prejudge any component. Feeling that it may not be worthy of a better power cord isn't the same as trying one and finding out for certain.

That said, if your system is resolving of differences in interconnect,speaker wire or component changes, then it should be capable of letting you hear what differences an upgraded power cord can make as well.

It's worth noting that the more power cords you change and if you keep them all the same,the better the end result is.

Expecting one power cord to change the sound of the whole system can be just too great an expectation.If one expects the sound of the High End,from entry level gear, a single upgraded power cord won't do it.An upgraded power cord as simple as it sounds, can really just change the component it's used in.

If several expensive power cords from the same manufacturer is keeping you out of the fun, then DIY.
Use the same connectors and wire on all your DIY cords.

I realize folks like to mix and match, and find wires that give more bass to some componets that seem to lack it.
But having been that route,consistency,clarity and coherence is more of what I strive for,so I tend to keep all my interconnects and power cords,the same thru out the system.

The power cords, as original equipment with the Quad 63 back when they were new in the 80's,were minimal,but judged to be all you would need by the manufacturer.

Which is/was a pity, because the sound of those speakers clearly improves when you improve the power cord.The same conclusion with stacked Quad 57, Martin Logan CLS and Acousta x speakers.
The better the power cord, the better the sound.

I would suggest hobbyists to address all electronic components the same,and not discriminate or assign any sort of hiarchy to one componet over the other.
Think of it as a system.Upgrade as a system.
Only then will the sound of the system truly be transformed and the importance of the power cords will be revealed in full.

I stated previously, my first foray into dIY /upgraded power cords.

Since that time,over 30 years,the stock power cord has always compromised the sound in any component I've ever owned.
No matter how sophisticated or simple it is.
I said "can make more or less of a difference" not will make.

My experience (and others whom I know) dictates what I said and I stand by it. YMMV.
An upgraded power cord can make "less of a difference"?

In my experience and in every system I've heard one used,there was always a difference for the positive.

There will always be a difference, how can there not?

Every power cord , stock, DIY or expensive name brand has a different contruction and has been used for different periods of time,which could be beneficial or detrimental ,depending on which side of the burn in/worn out side of the fence you're perched on.

I suppose you can make the same statement with all things in audio?

So why bother with tube rolling or capapcitor upgrades if doing so will only make more or less of a difference?

If what you have been using only makes "less of a difference", then perhaps you should try a little harder and broaden your search.

The good stuff is out there.

And besides just being different, what you'll hear will be an improvement.

My experience,and that of all "others whom I know" who have done the same.

Peace on earth my friend.
