Kevin, I'm surprised by your post.  The sales pitches I see say that a power conditioner is a very important part of a good system.  Do you disagree?

I think it's absolutely snake oil. Any piece of electronic gear using the AC feed is designed to filter out line noise. If your amplifier is so poorly designed that it allows any AC line noise into your audio, you have a very poorly designed amplifier that probably should be replaced.

On top of that, any improvement of the AC feed, and I'm not saying there would be with this unit, would only duplicate the filtration already built into your AC device. All consumer electronics that use AC Power have EMI suppression such as AC line filters. SOP for any consumer electronic device designer.

And lastly, this filtering of the AC (60 Hz) power line cannot result in your amplifier suddenly having "deeper blacks" and "brighter highs" as many of the sellers of the AC power strips claim.

Now - having said all that - I do have a Belden power strips on both of my audio/TV systems. I bought them for one reason. They have surge suppression. Many years ago, our television blew during a storm. A lightning strike wiped it out. I have used surge/spike suppressors on my AC feeds to my audio gear and televisions ever since.

I mean really - if an external filter somehow improved the sound of an audio amplifier, don't you think that some of these high-end, super-expensive audio companies would include them? Of course they would. Same with a fancy AC power cord. They don't because they know they don't need to.

Kevin, I trust your judgment.  But the premise of all of these third-party items is that the manufacturers *don't* include the special-quality extras.  Isn't that right?

I think the premise of these aftermarket cords, cables, isolation tables, anti-vibration feet, absorptive materials, etc. is to make lots of money. Anything after that is just marketing 101.

If a company were making and selling something like a $10,000 amplifier and they absolutely knew that a different AC cord, special feet or a special isolation platter would improve the sound, they would include it. But here's the thing - they test their products and know what the output looks like into a speaker load. They probably have tons of real data showing how their amplifier performs. And I'm sure that they've repeated these tests with all kinds of variables like different AC cords or with the amp on different feet or on a anti-vibration platter. They know how this amp performs under varying conditions. That's how amp design works. And I'm sure they rely heavily on measurement science - an area I've made a living in for decades.

FWIW, I test amplifiers that operate from MHz to 100 GHz. I have to measure these amps under all kinds of test conditions like varying voltages, temperatures & power levels. Design & product engineers do everything under the sun to see if they can improve the device's performance and go through extremes to avoid anything that would degrade that performance. It's worth repeating that if any of these add-ons improved the performance, they would be added to that product before it shipped out the door.
