Cable Snake Oil Antidote

" Listen Mr. Smarty Pants, you don’t have to mention any names. Just cut and paste this pseudo scientific mumbo jumbo you’re referring to. " - geoffkait


Seriously??? Where does one begin....How about a full Youtube video presentation with rambling mumbo jumbo about improving current delivery of an amplifier by using a power conditioner AHEAD of the amplifier in the signal chain?? Would that be a good place to start "Mr. Smarty Pants"?  Did you just crawl out from under a rock or were you just joking with an insinuation that bogus mumbo jumbo isn't a huge part of Audiophiledum?

Check out the Audioquest "presentation" at this year's CES.

The BS, ahem, I mean "technical presentation" starts at the twenty minute mark.

So, what is it specifically you object to? Be specific and brief, if possible. Be advised I would tend - as an objective observer - to believe what an established, well-known and respected cable manufacturer has to say. 

pop quiz - If a pseudo skeptic says a manufacturer claims are pseudo science do they cancel each other out?

The fact that you had to ask for specifics confirms that you are in fact (shockingly...) clueless from a technical standpoint.  But don't despair. If you stop yabbering for a minute and actually read/listen, you might actually learn something today.
Every amplifier  has inherent current delivery limits - usually associated with the limited amount of magnetic flux that can induce voltage, and thus current, in the secondary windings of its transformer. Pulsed power supplies, while the details are a little different, suffer from the same limitations. It doesn't matter what you put in front of the amplifier (super duper "power conditioner"), you are stuck with this limitation. You can think of it as a big resistor connected between the mains supply and the load (speakers). You can boost input voltage all you want (not that any "power conditioner" does this anyway) and you won't get any more current any faster through the system to the load.  With excessive voltage drive on the primary, your transformer will ultimately reach saturation, overheat, draw excessive current, and melt if it doesn't have rail and mains fuses to protect it. It's a simple law of physics - specifically attributed to a person named Kirchhoff - perhaps you've heard of him? In the video, Powell claims increased  current delivery under transient loads but current delivery is limited not only by the transformer's magnet circuit, but also by accumulation of resistance in various factors like the power supply capacitors, output stage emitter resistors (if so equipped) and output transistor saturation. If you'd actually built a high fidelity amplifier, you'd already know this. I'm guessing you haven't.

They aren't "courses". They are called "majors". And it generally takes more than one "major" to have an adequate foundation to build/design good loudspeakers.
Electrical Engineering
Acoustical Science
Mechanical Engineering

This is why it's more than a little insulting when a fast talking marketing fake gets up on a stage and starts preaching about things he knows nothing about - current delivery, damping factor, slew rate, rise time, group delay, voltage regulation, psrr, cmrr....etc..etc...

It takes years of study to master these subjects. When people listen more to slimey salesmen than professional engineers/designers, it's not hard to see why industry professionals are somewhat miffed. Why would anyone work hard to educate themselves about the science if they could simply take some marketing "courses" and BS their way through to the next paycheck? Why insist on seeing a doctor to diagnose a challenging illness when there are so many nurse practitioners who can generate a faster diagnosis at 20% less cost?
