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

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".

@blumartini - unfortunately, your original post failed to identify price vs. performance by component.

I have investigated cables for many years and power cable improvement  seems differ with the component to which they are attached.
- components with "less-capable" power supplies tend to exhibit more of an improvement
- compared to the same cable when used on amps with massive power supplies, which tend to exhibit less of an improvement

e.g. my Schiit Bifrost DAC sounded much better with a Signal Power Cable, which made no improvement when connected to my NAIM amp

So what may appear to a "good" power cable when used on a source component may not be so good for a Power Amp.

Sorry to complicate matters, but Power cables can be pretty fickle

The only commercially available power cable that I believe has the best price/performance ratio is Nordost, because I have heard them make noticeable improvements in a system and they have models at various price points better suited to the different components.

I now make my own, so I stopped looking at the vast amount of offerings now commercially available.

Unfortunately, some companies out there offer products that are not much better than a piece of bulk furutech/oyaide cable with a couple of good connectors attached. These make it difficult for anyone trying to buy a cable that is significantly better

Greetings All,

After reading Jay Luong of Audio Bacon;s Review of 27 Best Audiophile Power Cords I must say that I was Impressed! Jay spent several months reviewing each and everyone of them in depth. I must say this guy is the "Navy Seal of Reviewers" !!!

I thought it would be exciting if he would join us so I invited him along with all the companies he reviewed to join us. I dont know if they all will but I am positive most wouldn’t want to chime in :)

In response to your question on gas powered generators.

Aloha BluMartini, I’ve done some A/B comparisons with the p15(A)and my 15 year old Shunyata(B) conditioner. The P15 showed 4% THD and a real choppy sign wave coming in and .3 THD going out with A very clean sign wave. On Kauai we have a combination of Solar power and Diesel generated power. Power supply can be very inconsistent at times so surge protection is mandatory. I have a "whole house surge protecter" on my incoming 200amp line with a dedicated 20amp line to my audio room for audio equipment.
On my amps there seemed to be little or no difference.
On my preamp there was an obvious difference. The highs were more extended cymbals were faster and sounded more real with more air around them. Side to side sound stage got wider probably due to better definition though out the recorded frequency.
But, the best improvement is in the phono stage and CD player. The phono stage (and preamp)plugged into the P15 made an obvious and very positive difference. Soundstage got even wider but also front to back soundstage was way more pronounced. Bass got very tight and was easily identified, verses being somewhat muddy and vague. Drum attacks were more startling. CD player was similar although the depth wasn’t as prevalent. I generally don’t sit and listen to CD’s. I could go on but I got to go to work. Needless to say it was a positive addition to my system.

Pretty much EVERY category of product has an extremely expensive luxury class of that product type.

It is only in audio I have seen such blatant crude behaviour towards even the existence of such a class in product and those they may be able to afford them.

It would be like a Toyota owners harrasing a Porsche owenr insulting them for buying such a thing cause their Toyota gets them from point A to Point B just like their Porsche.

You could do that analogy with Watches, Handbags, clothes literally any consumer product type.

Why is it only the Audio realm where the venom comes out like this just for the existence of that class of product?
