One of my regular reads is a trade magazine called Pro Sound News. I’ve been a loyal reader for many years and have written before about the educational value of these free, industry supported publications. I even look at the ads.
An add for Essential Sound Products caught my eye, as advertising for something like a basic power cord really stands out among full page adds for the latest digital mixers and speaker line arrays.
A quick look at ESP’s web site made it clear that this ad wasn’t about a simple power cable. Not when you’re talking about $159.99 for a 7 foot power cable.
We like to think that we know a little about power cables, so Essential Sound’s claim that standard heavy gauge power cables cause (their words)
-High Frequency Roll Off
-Blurred Imaging
-Bloated, Sluggish Bass Response
caught us by surprise.
There may be some small truth to the possible ability of a well engineered cable to deliver measurable improved audio performance (we use the word “may” here). There is absolutely nothing that a cable that delivers power for the last two meters of its travel to an amplifier (wall plug to audio device) can do to address possible deficiencies in the building wiring, wall plug, service entrance cable or the miles of wire that the power company runs to get to the point where ESP’s cable takes over. It’s a passive device and can’t put something into available power that is not already there.
Money spent on a well made extension cord or power cable with a large enough gauge to not dissipate power as heat is money well spent. Any additional expense would be better spent on upgrading your audio equipment.
