Really, I want for you to consider that question and answer that.
I will buy you a plane ticket to Miami..you come over and I will prove there is HUGE differences in the sound you hear
...changing nothing but speaker cables.
There is NO WAY you can tell me I'm hearing things..we are talking about something we do 24/7 365 days a year...and I just don't go around hearing things!
Its like trying to describe a rainbow to a blind person.
Esh, I am full of admiration for your passion wrt to music. Your passion is clear to see when reading that post of yours above.
But... (you knew there had to be a 'but', right? LOL)... when you say that a speaker cable makes the sort of difference you describe here, then all your credibility goes flying out of the window.
The reason is that there is no way in all of known science for this 'huge difference' to occur. Speaker cables have no 'magic' properties. The properties they do have (resistance, capacitance, inductance) are well understood.
Of these properties, resistance is the only one we need to worry about. That is because by comparison with the capacitance and inductance of the speaker itself, the capacitance and inductance of the wire are irrelevant in reality. What this boils down to is that so long as the resistance of the wire is adequate in relation to its length and the impedance of the speaker, then nothing else is going to impact on the ability of the wire to carry the current.
So, unless the cables you were using before were insanely thin (and I am guessing not) or insanely long ( and I am guessing not) then replacing them with another wire with suitable resistance characteristics will not make the least difference to the ability of the wire to carry the current along its length with no problems. You are never likely to need wire of more than 14 AWG in a normal home setup, and if you went to 12 AWG for 'peace of mind' it's unlikely to make any difference, other than being so thick it can be hard to work with.
All of this is simple, well-understood science that has stood unchallenged for decades.
Why is copper used? Because it has low resistance and is relatively affordable. Silver has even lower resistance than copper - but it is very expensive and the only benefit would be that it would let you use a thinner wire for the same result. No real benefit at all. Gold, commonly used in 'audiophile' connectors actually has higher resistance than copper or silver - but it does not oxidise, which can be a benefit of sorts - but mostly its marketing. You won’t find gold connectors in Professional studios for example.
Skin effect? Yes, this is an acknowledged effect where high frequencies tend to travel on the outer surface of the cable. It is a significant issue. BUT - only for radio frequencies travelling over miles of distance (eg along high power electrical transmission cables). In audio applications where the audio-frequency signal travels not for miles but for feet, skin effect has no audible consequences whatsoever.
All the other junk perpetrated by the marketing departments of expensive speaker cable manufacturers also falls apart when subjected to scientific scrutiny.
The best, full explanation of all of this that I have ever seen is here:
Speaker Wire - A History, by Roger Russell
Just have a read of it. It isn't heavy-going at all and IMO you owe it to yourself to read it and gain an understanding of how easy it is to mislead people if you are in the business of selling 'high end' exotic speaker wire.
EDIT: I forgot to add this: Esh, in your speaker voice coils there is some ordinary, standard copper wire. There is way, way more of this wire in the voice coil than in the length of wire you use to connect your speaker cables between your amp and speakers. So why doesn’t all this 'ordinary' copper wire in the speaker itself just 'remove' the effect of the 'special wire' which connects the speaker to the amp? Any views?
