>>I've just heard too many bright cables (interconnects), and opinions about silver being inconsistant from one manufacturer to the next, (but what product isn't?). Maybe they got it right with the Xstreams?<<

they got it right with excaliburs and sorcerers for sure...

Any thoughts on this Silver Plated Copper Belden Star Quad Cable? I just picked up some from Giant squid

Bush has some cables made with this. Used them & loved em. Very compact.  

http://www.giant-squid-audio-lab.com/gs/gs-custom-cables.htm
Scroll to the bottom.

I would imagine they're nicer than standard copper and I think I see why they pate copper with silver but for mic cables I don't know if it's as helpful as it is with speaker cables?

The silver plating is great with transmitting AC due to skin effect (AC like to travel on the outside of the wire).  But I would think 48 volts Phantom is DC so the entire wire is being used equally...no?

The Spellcasters sound exceptionally sweet. Clear, defined, not bright at all...

yeah, spellcasters are between excaliburs and sorcerers.  i like all 3.  never heard the illusions or clairvoyants, but i imagine those are a little sick too :)

George Cardas' view on the silver debate:

(Full article at:  http://www.cardas.com/faqs/index.html   Lots of other good stuff at http://www.cardas.com/insights/index.html )

Copper vs Silver
Q.) Why hasn't Cardas manufactured a silver cable? -Tank

A.) Many manufactures have experimented with silver and other metals in the development of their products, and most have decided that ultra pure copper is the best conductor material. Cardas manufactures most of the silver stranding used in the industry, but the fact remains, ultra pure copper is generally better as an audio (AC) conductor.

The highly refined copper we use has a DC conductivity of approximately 103.8. This is within 1% of Silver's DC conductivity, but the critical differences here are copper's slightly lower inductivity and skin effect ratios that make it easier to work with in audio (AC) applications.

This is not to say that some embodiment of silver could not compete. There are ways to make an excellent silver interconnect, but given the costs involved and the inherent problems with silver, I believe the money is better spent on conductor geometry.

In interconnect cables, where capacitance is more of an issue than inductance, a silver conductor could have a small advantage. Silver's downfall is its low internal damping or loss ratio. It is like a speaker box with no internal damping, you end up with a very efficient speaker that does not sound good. The tendency for a slightly forward, hard or bright sound is always there. My initial work with silver in Golden Ratio, Constant Q, Litz configurations is encouraging, but I haven't come up with a configuration that I care to live with as yet.

I'm not ready to consider silver speaker cables. If there is any advantage, It would come at a price that seems over-the-top to me. I think I will leave the Black Pearls to Ray for now. -George

Oxides of all(?) metals are known insulators (or at best they have distinct rectifying properties.  CuO2 was for example used as rectifiers in antique radios. ).

That's what the oxygen does, it captures the electrons in the conduction band and reduces the overall conductivity.

You do not want oxygen in your Cu cables. Now, if the effect of a small contamination is audible...  well that discussion has been raging since ehh ohhh the the dawn of modern time? :-)
