I'm going to say it again and wait for somebody with better knowledge to shoot me down.
Wires typically have three main electrical parameters.
Impedance/ resistance.
Capacitance.
Inductance.
Together, the above constitute a filter.
These parameters are measured in units something like ohms per kilometre, etc. In short, over the length of 'Yer average' domestic speaker wire, the effects of wires electrical parameters will amount to the Square Root of **** all.
It follows, to me, that no properly constructed wire will make an audible difference to the signal.. and further, any cable which does make an audible difference is deliberately engineered to do so, and therefore dishonest.
I use Mark Grant assembled Van Damme Blue.
It works.
