The Truth About Power Cords and there "Real" Price to Performance

The transient demand of a power amplifier is much higher than that of the power tool.

Add in, is that the transient demands are all over the map and always happening, and with a veritable infinite number of conditions...with the amplifier.

And then added in again, on top of that..is,...that humans hear principally via that transient and all complex transient systems...and we define our hearing limits in the small tiny area of perfection of delivery/shaping/levels/timing of those complex transient loads.

the above allows one to begin to define the question, so they can begin to shape their understanding why power cords make a difference.

Wow, this has been an excellent thread thus far. I never know where things are headed when I post a thread, its like being blindfolded on a roller coaster ride! I am thankful to all of you who have contributed as we all can always learn no matter how large or small your system is or how much you know or think you know there is always someone who knows more than you! Now as far as the "Kamikaze’s" out there dive bombing with snide remarks and negativity please be more respectful to the group some of us are here to learn.

Thanks again to all.

Cheers!

You would think with all that cost of the SR and ET power conditioning units, that they would get rid of almost any noise.

That 10A Skillsaw can draw 60+ amps on startup, and can also draw temporarily when loaded much more than 10A as well.


A large ClassAB, ClassD, or Class A/AB amplifier turned up loud can also pull greater than 15A for a small portion of the AC waveform, though unlike the Skillsaw, the average current won't exceed 15A.

The Skillsaw I was using had more power and came up to speed quicker and felt like it had more torque than a lower grade cable. I have always believed that the start to a better sounding audio system starts with what comes out of the wall socket first. Better cables and noise reduction treatment is the start of a great sounding system, (Crap in, Crap out).

There is nothing factual about claiming that humans hear "Principally via that transient" or most of the rest of that paragraph.

While it is true that the initial arrival wavefront is dominant in sound localization, that is primarily due to group-delay/phase based inter-aural processing (difference in what reaches each ear), not in the exact shape of that wavefront. We also give dominance to processing of the initial wavefront and reject echoes and reflections, to a degree, for transient sounds, which gives credence to the importance of transient response. The brain tends to lump the first 35msec of the transient together, so transient has to be put in perspective.

However, to say this is "principally" how we hear, is just not at all supportable. It is not even supportable for localization which includes level cues, frequency cues, etc. which in music can be as important as timing cues. It is just a part of our auditory system for processing threats. Evolutionary changes to support speech and better interpret threats greatly extend what it means to "hear".
