Speaker Wire material

The physics of it is hardly "just pushing electrons along the wire". Where's Maxwell when you need him?

Regards,

My understanding is that the oxides and/or impurities of the two metals have different conductive properties and that is where the main difference resides, everything else being equal. Regarding physics, keep in mind that the electrical properties of the overall cable design also affects the sound of a cable - materials being only one part of the equation. Consider overall impedance, as well as capacidance and series inductance. In my experience, series inductance has the most effect on overall cable sound. Consider that cables must transmit short term transient signals, and that inductance resists signal changes, and maybe you can see my point. I have found that very low series inductance cables sound best. Keep in mind though that most cable manufacturers don't publish their specs, though I wish they would - that way maybe we could develop a worthwhile coorelation between measured specs and empirical data. This is just my opinion :o)

Trying to use physics to explain the differences between copper & silver wire will not change the fact that they do produce a different sound. If I recall, Glen Croft said that the use of all silver wire in a component would produce an undesireable sound. However the combination of both copper and silver wire is more desirable.

The two metals do sound different too my ears. Real Silver has more of a silkiness to the top end. So far that's the biggest difference I notice.

SLV:

Consider the mass balance of the oxide to the unoxidized metal... You will see that this means that the electronic behavior of the oxides cannot be significant. (same applies for other "skin" effects" arguments)
