A while back I offered my thoughts on a particular type of over-priced and over-hyped audio snake oil, namely power cables. So today I get my new issue of Bass Player magazine and what do I see? Why it’s an add from Essential Sound Products hawking their MusicCord AC power cord with the headline “Your stock power cord is choking your sound!” If you go to their site (which I won’t link to) you will find unsubstantiated claims about other AC power cords producing “Thin, One-Dimensional Tone; Attenuated, Gutless Bass Response; Hiss, Buzz and Noisy Backgrounds; High-Frequency Roll-Off; Blurred Imaging; Bloated, Sluggish Bass Response” and other issues. Geez, I certainly wouldn’t want my bass guitar to suffer from “Bloated, sluggish, attenuated, gutless bass response”. Granted, I always thought that “bloated” was rather the opposite of “attenuated and gutless” in this sort of situation, but perhaps normal AC power cords are worse than I thought. Of course, you won’t find anything on their site in the way of serious double blind listening tests to validate these claims. As I offered a light critique in the afore-mentioned post, I won’t rehash it here. I only have three things to say regarding this company right now:
1. Apparently they have discovered (or are at least hoping) that naive musicians offer a profitable new market beyond tweak audiophiles. And hey, given that higher end basses are in the multi-thousand dollar range these days, maybe $100 for a power cord is well within the budget of the “tone paranoid”.
2. Not to be outdone by the power cord, the company also offers a six outlet power strip. With surge suppressor mind you! On sale, the bargain price of just a dollar short of $500. Why, you save $100 compared to the normal price! Gee, I can think of an alternate route: Go to the local hardware or electronics shop, pick up their most rugged surge suppressor power strip, give $100 to charity, buy a new stomp box, fold up a bunch of $20 bills and stuff them under the leg of that wobbly table in the back room to level it, and you’ll still be ahead.
3. They are not the worst offender. Look at this. That’s right, $3500 for an AC power cord. This is nothing short of vile.
While searching for some material on this topic, I came across this article discussing whether or not there are audible differences attributable to power cords. When I got to this part I just had to laugh:
To many in the engineering community, blind ABX is an accepted experimental design. Using the blind ABX protocol, we failed to hear any differences between an assortment of generic power cords and Nordost Valhalla. Therefore, we cannot conclude that different power cords produce a difference using the blind ABX protocol. However, we also cannot conclude that there are no differences. We simply failed to prove that differences can be detected to a statistically significant degree using a blind ABX protocol.
So in other words, if a proper double-blind test doesn’t reveal any differences, the only thing you have shown is that a double-blind test doesn’t reveal any differences. Apparently, there are no further consequences or conclusions to be drawn and it has nothing to do with what humans can or cannot hear. Brilliant!
