Are silver cables best for my system????

In my experiences, silver cables tend to be more revealing and transparent, while copper cables tend to be warmer and more musical. This is a generalization, but I've found that it holds true for me.
Now, each will shine it the right system. I've found that silver will sound best in tube systems and/or with warmer speakers. While the copper will sound better with solid state equipment, and/or with speakers that are leaner sounding. Neither copper or silver is better, they both are system dependant.

So I wouldn't say that your cables are too good for your system, but I would say they aren't a good match for your system. Try some nice copper interconnects.

Cardas interconnects might be the right touch.

Audioquest silver offers the best of both worlds. Not inexpensive but worth it.

I've noticed the same as Jmcgrogan2. My silver cables were very detailed, but a little bright. I always go with copper now. But I like warm and fuzzy.
