My experience has shown me that under no circumstances will I use silver in a system. Silver sounds clear, clean, but also white, bright and harmonically threadbare, worst of all, silver has artificial and anaemic sounding timbre. That last property is in my opinion a death Nell to building a great realistic sounding system. If a system needs a dose of silver flavouring that's telling you something loud and clear. For example if your system is dark thick and lacing transparency, silver acts like a band aid. Sometimes this coloration seems to improve your sound, but ultimately that system will never reach an elite status. In reality Silver is a nice band aid to get a poorly tuned system out of trouble. Copper has all the ying and yang needed to tune a system correctly. If you try various copper types, example, solid core with different diameters and manufactures, multistrands from various manufactures, strand amounts and most importantly gauges. Attributes, Solid core has a full solid, grainless, midrange orientated, quality, with good base weight, but lacking some air and apparent frequency extension. Multistrand has air and a bigger 3 dimensional and layered soundstage, perceived detail and high frequency extension, but with the baggage of possibly sounding grainy and brittle particularly in the high frequency's. I usually use mostly solid core, and in the final tune stage, and try various multistrands types in selected signal path areas, till its right. Copper can and does have the necessary Ying and Yang to cover the complete spectrum. It's up to you and your ears, to just juggle the wire or parts combinations till you are happy with the balance. The bottom line, i have never in 40 years heard a truly brilliant, amazingly real sounding system, wired with or containing anything silver. Silver in a system just never sounds complete.
