The Physics of Electricity


Can anyone explain clearly in either common parlance or technical terms the difference between a $1,000.00 cable and/or speaker wire versus a $20.00 (or so) one? What does wire "do" in an expensive cable/wire that an inexpensive cable/wire does not? Does it conduct more or "better" electricity?

Exactly what I was trying to convey. Differences in naterials, insulation, conductor size and composition, and manufacturing result in measureable differences in impedence and capacitance. These differences will alter the sound from dark to bright, and from slurred through smooth to detailed. I recommend starting with a well made, good copper, affordable cable and then adjusting for what one wants in the sound . . .brighter and more detailed (consider silver). . .darker backgrounds (consider AQ Midnight). . (more bass consider larger conductors)..and lots of others to one own taste and budget. However, I would NOT attach a $2000 cable to a $350 amplifier and expect a megashift in amplifier performance. I would consider dedicated lines well BEFORE I spring for expensive power cords; I am sure others will weigh in on this, but please let common sense and blind listening tests direct your choices.
Kijanki, is this when "quality" electrons make a difference?? They really improved the performance of my bucket of steam.
"is this when "quality" electrons make a difference??"

That's right. As we know electrons only shake in place at AC when electric charge moves. Young electrons shake eagerly while old stale ones don't want to shake. All is in the electrons! Wanna buy some?
Kijanki, what's sad is I understand. Thanks for the offer, but I like "shake and bake" KFC.
Wires are like ice cream. They come in all different flavors. The good ones are the ones that sound best in your system. Cost is not an effective determiner of end performance. Great sounding wires might cost just a few dollars or thousands.

One feature that clearly matters in many cases is whether the wire is shielded or not. Unshielded wires can pick up noise from nearby electronic devices more easily. Digital devices, switching amps, and power amps or other household devices with large power transformers and RF noise from radio waves are the common sources. LOw level signals like that from MC or even MM phono carts are most susceptible, though line level sources including the signal from pre-amp to power amp can be affected in a quite negative manner that may or may not be apparent from listening by these kinds of EM and RF fields.

I also tend to like wires with network devices that attempt to maintain constant electric properties like impedance by design regardless of length, etc.

It gets a lot greyer after these few things to me.....

DNM reson ICs are inexpensive, simple, and golden in my estimation however are not the best choice in some applications where a shielded wire is called for.

Even teh inexpensive networked ICs from MIT are very good. These are also shielded I believe.
