Differences between cable sound.

there are other factors besides metal that determine a cable's performance.

there are several cable manufactureres.

here are three:

aural thrills
pear audio
fusion audio

i own fusion audio cables and have owned aural thrills interconnects.

i also own the capativa continuous cast silver interconnect. it is balanced in its frequency response. it is a very pure silver.

I like silver with a PE dielectric and prefer using it with tube gear. SS gear and things can get a bit hotter on some recordings. I like silver coated for general use, and it us good for most things.

If you listen to Jazz and Classical i.e.,acoustic music,copper is best unless you REALLY have near-perfect system.
For rock doesn't matter much, loud and coarse anti-cable is more than enough.

There is some very interesting stuff here, not the least of which is the fact that Elizabeth and Schubert appear to be in agreement. After spending considerable time trying to wrap my head around that, I will make this comment. I have had good and bad silver and copper cables. I recently added a silver IC (VH audio Symmetry)and found that it did wonderful things--sweetened the top and significantly increased resolution without adding any brightness at all. It is an excellent IC! Appart from that, the rest of my cabling is Audio Magic Liquid Air. The LA's are also very good. This is a non metalic conductor which I think more people would do well to try. I think its character is a bit more like a very good copper than silver. Low grain, good dynamics, great bass slam. I think there is virtue in mixing cable types. It could be that adding silver to my existing Liquid Airs was just the right touch. I think both VH audio and Audio magic make great bang for the buck products. Not as cheap as blue jean, signal, etc, but they are very good.

for the record i find fusion audio romance gold interconnects superior to any silver or copper cable i have heard.
