If you're being sarcastic then proceed, I don't intend in trying to discredit your 2.5 decades, but I can show you sound samples, one of the cables was significantly fatter sounding.

(Edit: If anything, I joined this forum today to learn from people like you.)


No  I'm not being sarcastic at all. I'm not disrespectful to people like that.    I know cables act like filters. I've had 25 years professional experience mixing TV shows and even more as an audiophile.   Also EQ is a filter.  I can EQ many different microphones and make them sound similar to the point where it will be hard to tell them apart in a mix.  I've done it countless times in TV shows.

Why would we want to be disappointed with something? I've never understood this argument. For example, I spent several hundred dollars on a KAS Audio Kaiser XT cord. It was huge, the size of an Aural Symphonics Magic Gem. So it's got that "big = good" thing working for it, plus all of the info on the KAS website telling me how much work they put into the design and how great it is. So I have my considerable investment, plus the visual aspects, and the marketing, all pushing me to imagine that it should kill the other cord I was using (smaller, less visually impressive, less marketing effect). And.... I hated it. Every component I tried it on, it just seemed to strangle the life out of. If power cords have no effect other than placebo, why would I imagine it to stink?

 




Exactly, it is all about getting the equipment to work together. It is more than EQ, without sounding silly .........Do you know how they teach refraction of light to kids in school without going into the technical jargon? Picture a group of runners all trying to enter the ocean and swim. All can not get into the water at the same place so some go around to get into the water. Thus you see white light bent into all the colors that make it up.

 

Refraction is the bending of a wave when it enters a medium where it's speed is different. The speed is different because of the material.

 

I am guessing here. Imo, I think there is a correlation between light and electric signals traveling through a power cord or interconnect. It is much more easy to understand this with interconnects and tone than a power cord.

Both are energy and both are changed by the material they pass though.

 

 

In physics at this point there is no papers on a relationship between light and electricity acting this way but if our cable questions are ever answered by a type of physics math I feel it will look a little like the Snell-Descartes law for refraction.

 

We have only been rapidly developing the use of electricity for 100 years. Not all is known about the slight effect metals have on current.

 

In optics and physics, Snell's law (also known as Descartes' law, the Snell–Descartes law, and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water and glass.

 

In the above paragraph the other waves we are talking about here is sound.

In underwater acoustics, refraction is the bending or curving of a sound ray that results when the ray passes through a sound speed gradient from a region of one sound speed to a region of a different speed. The amount of ray bending is dependent upon the amount of difference between sound speeds, that is, the variation in temperature, salinity, and pressure of the water.[4] Similar acoustics effects are also found in the Earth's atmosphere. The phenomenon of refraction of sound in the atmosphere has been known for centuries;[5] however, beginning in the early 1970s, widespread analysis of this effect came into vogue through the designing of urban highways and noise barriers to address the meteorological effects of bending of sound rays in the lower atmosphere.[6]

 

So far we have seen that there is underwater acoustic refraction, acoustic refraction in the Earth's atmosphere and light refraction.

 

If a copper wire is connected into a series circuit with an aluminum wire of the same diameter, the charges in the copper will flow slower. This occurs because there is one movable charge per each atom in the metals, but there are more atoms packed into the copper than into the aluminum, so there is more charge in each bit of copper. When the charge-sea flows into the copper, it gets packed together and slows down. When it flows out into the aluminum, it spreads out a bit and speeds up. This means that we cannot know how fast the charges flow unless we know how dense the charge-sea is within the metal.

 

In these issues of refraction the relative density of a material changes how the refraction takes place. Diamonds are high on the density index so more refraction. As I understand it the photons of light are slowed more thus a longer prism effect on walls when light goes through diamond. Glass less as it is not as hard. The temperature, salinity and pressure of water are also changing the refractive index thus a different refraction of sound waves. I would guess that this same truth holds true for sound passing through matter of different relative densities. The end statement here is that I feel it is a very real area of study to find out if the charge sea, photons, and sound wave energy act the same when traveling from one area of molecular density to an area of higher molecular density. It has been proven completely that sound waves and light do react this way.

 

This could explain why the cables only work on some of the equipment. One part of the equipment is the same relative density metal for the charge sea to pass though. The change occurs when the cable material is harder and the charge sea slows down. We know that silver has a specific gravity of 10.5 and copper is 8.9. This to me is the ultimate guessed explanation of why the material sounds so different when used in cables.

Redcar I was researching LF pulse waves and came across this, sort of reminded me of your line about light and electricity in an off hand way.

If a thin wire is connected in a circuit end to end with a thick wire, it turns out that the charges in the thin wire move faster. This makes sense, it works just like water in rivers. If a huge wide river moves into a narrow channel, the water speeds up. When the channel opens out again downstream, the river slows down again. The flow in a very thin wire will be tend to be fast, even if the value of current is fairly low. This means that we can't know the speed of the flowing charge-sea unless we know how thick the wires are. This is why bigger is sometimes better!

 

 

 

 

It is a combo of charge-sea hold of atom per area of metal and amount of metal used in cable.

 

 

 

 

Any person with an electrical engineering degree here will agree with the above, hands down.
