My personal experience with silver speaker cable and interconnects is that they are faster, more detailed, and more transparent than their copper counterparts. They also tend to lack the weight and body of copper as well. Therefore, component matching and break-in are very important. If your system is already generous in the bottom-end, silver may be just the ticket. Without proper break-in, silver can definitely sound annoyingly etched.
Does silver speaker wire sound bright?
I purchased a kit of 99.999% pure silver speaker wire with PTFE insulation and assembled it. I installed it on my system and it seems to scream at me. My system is all tube (Melos)and my speakers are the North Creek Rhythm. I use the preamp also as a headphone amp and use Grado SR325's. The headphones are not bright they lean tward a little dark sounding. I feel the brightness is in the cables and wounder if they will mellow with age, and how long will it take?
