Snooks' observation matches one that I heard a couple of years ago in my home. We had a new speaker being demoed for the NJ Audio Society in my home, which used a copper jumper between the bass section and the separate tweeter-midrange module that sat on the bass cabinet. As we were positioning the speakers, for fun I put in my Kimber Black Pearl jumpers I then used for my speakers in place of the copper jumpers (a 6 inch length). The speaker designers were stunned at the better clarity, dynamics and overall tonal and harmonic truthfulness resulting from the change; we used the jumpers for the demo.
My system currently uses copper interconnects all throughout (I'm pretty sure the NBS Omega is copper) except for the Graham IC-70 arm cable; in the past I've not liked the sound of silver in my system for the reasons Tim (Tireguy) mentioned. I'm now re-thinking that, and I'm trying Siltech's new G5 interconnect between my phono stage and preamp. The latest silver designs seem, at least in limited demos I've heard and definitely in the new Graham armcable, to have become far more natural and full-bodied than the older designs I remember. Ultimately, the differences I'm hearing are probably more a result of other factors in the cables' design than the type of wire involved, though, as many of the other posters here have noted.
