Pc123v .... cool your jets until I finish my romex experiment. Pure copper ... ultra pure ... hyper pure. Dielectric properties of insulation. Reminds me of the Space Balls movie when the baddies went to "Ludicrous Speed." Voodoo. Snake oil. Bull sh*t.
you might think that this is all bullsh$$ but some of it isn't!
I've tried Romex 14AWG wire as speaker wire while I was awaiting my speaker cables. Yes, it delivered an electricak signal from the amp to the speaker so I could listen to music but that's about all it did.
The purity of the copper used does make difference. Better brands of cables use OCC copper & I found that does make a difference.
Insulation is another big factor. Romex from HomeDepot or Lowes or Ace uses PVC insulation which has a very high dieclectric constant which I found muffled the sonics & made the imaging imprecise.
Yet another thing that works against us when we use heavy gauge wire is that the wire vibrates (mechanical vibration) when there is a music signal passing thru it. Rick Schultz of Virtual Dynamics (Canadian company that used to sell OCC copper based heavy gauge interconnects, speaker & power cables) spent a lot of time figuring out how to damp that vibration. His cables ended up being ultra-stiff & ended up being a pain to us but some of his upper tier cables were really very good sounding. I used Virtual Dynamics cables thru-out my system at one point (I still have his Nite Platinum & Revelation 1 power cables) so I have personal experience. Using a heavy gauge cable without damping is going to make your music sound dull (as I experienced).
I believe that you do not have to spend mega $ on cables but you do need to pay attention to the materials used & the design.
There was an excellent thread on cable design started in March 2013 (where Almarg also participated). I think it is very worth your time to read that thread - it has great info on cable design & what to look for:
