I don't want to dispute your personal findings; however, it does not seem likely that a power cord could make blacks display blacker on a monitor. Black is created by the absence of light, so you're basically saying that, not only does the super cord deliver more current, it also can create less than zero current. Can't get any blacker than off. What you see might possibly be an illusion. Kinda undermines your claim.
External factors—portability, mobility, etc.—justify whether to use wireless instead of a cable, not reliability or performance.
Bob - Give a Music Cord Pro a try - if you don't like it - or can't hear the difference - send it back. Audio Power Cable Hi Fi Audiophile Guitar Bass Pro Audio Power Cord | Essential Sound Products Tell 'em I sent you.
In video, producing black is the equivalent of an audio amplifier producing low-end response. Colors (whichever one) are like high frequencies in audio. The only reason I mentioned this is because most people believe what they see more than they do what they hear, even though your ears are much more accurate than your eyes are. In the Music Cord Pro, the combination of 8 x 20 gauge conductors in series, has less resistance (lower impedance) and it gets power into whatever device much faster than a 16 gauge IEC cable with 3 conductors. I've recommended the Music Cord Pro to a bunch of my friends and every one of them heard the difference. Its built very heavy-duty too.
Please send me your list of friends who all heard a difference. I've got a bridge in New York I'm looking to sell and they're exactly the kind of buyers I'm looking for....
You got to love it when someone is so fooled by his own confirmation bias that he tries to convince a well respected engineer that the snake oil is for real.
So why should I expect it to not behave like a power cord, and instead do things that a power cord doesn't do?
Well then, if its all about having the resistance of a 14AWG conductor (what the Music Cord Pro web site claims), then have at it. 14AWG 10 foot IEC cable from Amazon. $12.50 with free shipping.

This is horse puckey. ESP's explanations of the "science" behind their power cables is laughable to anyone who actually understands how power cables and amplifiers work and an affront to real engineers. It's a bunch of pseudoscientific bafflegab meant to impress people who have vague ideas about the mechanics of power delivery. It's insidious because they use real concepts but grossly misapply them to audio. The skin effect, for an example. This is a very real thing and is actually quite problematic in transmission at RF frequencies, which is why you see flat cables and Litz wire in those applications. However, it is of no consequence at audio frequencies, even if we generously extended those out to 100kHz. And the idea that current delivery from the AC line to an amp's power supply can be somehow "sped up" by a 6 foot special cable is ludicrous beyond belief and indicates at best a fundamental misunderstanding of how power supplies work or at worst a deliberate deception.
Increased Dynamics, Volume & Headroom Your amplifier will be capable of playing louder yet sound effortless! My amp can play louder, but sound effortless? How do I know it's effortless? What does effortless sound like? Man, you just can't write this sh*.... oh, wait... Hey now, I've bid on that bridge. Please do not assist in bumping the price. Thank you.
Apparently, power cables can cure GAS. Most Affordable Way To Improve Your Sound! Once you try MusicCord-PRO and experience the magnitude of performance improvement, you may no longer feel a need to replace your component. This could save you hundreds to thousands of dollars!
If you have any of the above between you and your amp, the solution is not wireless, the solution is a kick up the BL's backside for booking you into such a venue! Then make him go and turn your low mids up a half-notch.
Nothing against ninjas, sharks, or pirates at a show, just not between me and my rig. I just broke the singer of that habit...
I bet Einstein would have loved to know how this happens. There truly is so much tripe in this topic that it's being used to great effect on some forums where the members here are being laughed at. The physics is solid, the bent physics so full of holes, even a high school student would shoot the rubbish down in flames. The only real physical difference between cable (and NOT expensive vs cheap) is really attenuation and capacitance. So a cable can have negative impact, if it's characteristics are at odds with the source and destination - usually due to impedance mismatches. This is it. Most suitable cable is also quite thick cable, so is also rugged, easy to solder and age resistant. I've been using the same main cable sources for getting on for twenty years, and the old ones are just as good still as new ones. All this magical snake oil stuff just makes people laugh.
