Speaker cables.. Budget again.. With a twist...

Leaving science and theory aside, the contention that auditory perception is a reasonable basis for choosing one cable of the same guage over another is also flawed. I am unaware of any studies conducted with reliable controls (i.e. double blind studies conducted by an uninterested party) that show that humans can tell the difference between such cables. The last I heard, audiophiles could not tell the difference between metal coat hangers and specialty cable. What is argued to show this difference is offered as emperical evidence, but is no more than anecdotal evidence. One can find anectodal evidence to prove anything - sightings of big foot and ufo's for example. By the way, I concur with Sinisterporpoise68 - Belden cable works great. Belden has had a consistently good reputation for decades and is an industry standard across applications. Furthermore, Blue Jean Cable has a relatively low markup. To get it for less one pretty much has to buy large fairly large rolls.

"At any rate: Electrical or Electron Theory is still just that. The theories that have been put forth concerning electron flow can hardly been observed at the Quantum level at this point in time, thus they are not observable."

That may be the case, but the EFFECTS of electron flow CAN be observed, repeated and measured/recorded. It may be referred to as "theory" but the reliabilty of it is undeniable; otherwise a standard light bulb wouldn't work, let alone any complex electronics like computers or audio gear.
It is often the case that observation and measurement of an effect is worth as much as observing the subject. Astronomers can locate and study black holes or new planets by the effect they have on their surroundings; we don't dismiss such science simply because the planet or black hole has not yet been studied.

Back to wire: I've chosen (relatively inexpensive) silver over copper wires for my speakers based on a slight lift in the upper frequencies this produced, and I have heard improvement from a cheap 'supplied' IC to a high grade aftermarket one.
However it bothers me that some here fall over themselves to believe the pseudo-scientific claims made by some expensive cable makers, and then dismiss established electronic and metallurgical science when it suits them.

Go back to Home Depot and get THHN. These are relatively thick and they don't bend well, but there is nothing better at that price point. You will need 4 cables...all the same length. Put spades if you can find them on the ends..or rings if you can use them on your amp/speakers connection. If not, you have to use a saw, or tin snips to cut these to make spades..The spades should be the ones that have a screw to secure them. Don't solder them..it will decrease the performance. You have to spend WAY more money to get anything better than these...especially at those lengths. I can surely guarantee you will be happy with these until you can spend mega bucks for the high priced spread.

That we can measure amperage, impedance(or resistance), and capacitance is not in question. A music signal is much more complex than the AC current that it takes to light your light bulb, containing a plethora of frequencies, harmonics, ambiance and timbre cues, etc. Much experimentation has gone into the dielectrics, conductors(OFC, solid silver), and configurations(Litz, spirals, etc) chosen by some of the better cable/interconnect companies over the years, and the fruits of their labors are greatly appreciated by those of us that have taken the time to audition and use them. That some have chosen not to, doesn't surprise me in the least. If everyone chose to follow those Pie-Eyed Pipers of everything-sounds-the-same/there's-no-difference/don't-bother-trying: We might still be listening to a conch shell held up to the ear. Probably not two for stereo, because that would have been discouraged also

Which side of this debate has the most enthusiastic "Pie-Eyed Pipers?"
