I have my reservations regarding spc. it is also noted in further reading that the dissimilar metals react and cause a "cancer" in the cable that if I recall correctly, might be called "red oxidation"? (It's been a long while since I read that, and I dont recall the proper name for the oxidation condition though).
more reading bits (and this might help in explaining Scotts comment of a "film over the vocals" ((a paraphrase)):
At audio frequencies, otherwise small differences in simple DC resistance significantly alters impedance. Therefore, the presence of both silver and copper in the signal path is capable of creating two different, frequency dependant, conductive pathways to the signal which is a non-linearity that NO audio cable should be causing, especially not a "high-end" audio cable![/url]
I hold great reservation on the "technical opinion" held by infommercials and sales websites.
I'd like an independent lab and some science, please !
I posted that because it supports the point I make about trace voltages and metal incompatability, not because it is solid unbiased research. I don't need white papers to tell me what I've encountered in real life in dealing with metal incompatability, and I can easily assume what i've learned in marine applications, and apply those assumptions to other forms of incompatabilities.
have you ever dealt with metals that have been corroded because of incompatability, galvanic distortion?
*example: an aluminum boat that is moored next to a bronze tillered sailboat, 15' away, will be dissolved at a steady pace until it sinks, unless proper anodes are placed for the corrosion to occur.
They seem solid until they crumble. By introducing two malleable metals with an extremely high rate of natural oxidation of there own, and you cross those metals, you are introducing trace voltages that are measurable, and destructive (extremely destructive in the marine environment).
Why introduce something that is going to be producing a trace voltage on its own?
You cross two incompatable metals, you get electrical voltage. Audio signal is voltage, and impedence dependant. Why introduce something that is prone to this?
edit: removed dexter from the quote, and added *example
Point well taken !
I'd assume that the silver-plated copper wire uses alloys that are compatible.
Silver and copper are similar, but I left my Periodic Table of the Elements on my 11th Year SAT desk and never looked at it again
I know silver-copper won't make a battery, but it may depend on the metalurgists hand as to the alloy.
I'm not trying to play the devil's advocate too much, but I just want to keep the idea that vendors can bend the truth a bit in play.
My toolbag has some WWII surplus silver-clad copper that has silver tarnish on the exposed ends, but is otherwise pretty clean.
Silver tarnish is conductive, FWIW. I don't know if it affects sound, to those who can hear interconnects.
I can't hear differences significant enough to warrant huge upgrades. I usually hear changes in barometric pressure and sonic-memory to a much, much greater degree !
BTW, how'd you fair in the Tsunami scare ?
