Hey HTcOz,
In regards to your line of questions... Let me give away a little info about that.
It is not just about the wire. Sure high purity OFC is great and does have an effect, but that is but just a drop in the bucket. For that matter, the jacket type has as much to do with how it sounds as the wire itself in most cases.
It is not about inductance, capacitance, and resistance, but they do play a role. Bigger gauge and lower resistance in itself can have some subtle effect in the bottom end, but less than you'd think.
The power cable can be anything and everything between being an antenna and being a filter.
It can catch and transmit tons of EMI, and RFI signals along with that 60Hz AC sine wave.
Or it can be designed in such a way as to cancel out, reject, or filter a lot of that stuff away.
Power cables can't give you something in the music (in the recording) that is not there. In other words, it can't create sound stage depth, width, space between instruments, etc. However, it can obscure those things. In other words it carries with it all kinds of bad things that destroy all the good stuff. Strip that bad stuff away and the good stuff about the recording can then not be obscured and masked over.
Make sense? Some think that the AC power cables is that last thing in a long chain of power coming from a power plant to your gear. But it is really the first thing that your gear sees. And that thing is either collecting the bad stuff, or filtering the bad stuff.
Adding something like the Majik Buss just takes it all several steps further still.
Let me add a little to what Danny has said. I like analogies, so here is one:
Powering a system is a lot like getting water from a well. In that well with the water are bugs, rodents, bacteria, rocks, dirts... all the kinds of things that make me a poor camper. I hate 'em. I need the water, but I DO NOT want any of the aforementioned. So, what do I do? I build a series of traps and filters that take all of the bacteria, roaches and dirt out and create a maze that the stupid rats can't get through.
That is what is going on with passive power components like power cords, CorComs, ferrite beads, my filters and on and on. Some of these devices just work better than others.
In audio, whether we like it or not, everything effects everything else. The quest towards superior reproduction is a trail that has many twists and turns. I have about a gig of notes that I have compiled over the years from experiments performed that includes all of the successes and failures. A few years ago it became very clear to me that audio reproduction, just like everything else, has to be built upon a firm foundation or the whole structure is weak. Ergo - my power treatment products.
You just have to be smarter than the rat.
