Copper v. Silver

It all comes down to your ear. Listen to a good silver cable then switch to a good copper, the a hybrid copper silver.
I recently replaced my AudioMagic Excallibur II's ( a silver
cable) and wnet to the Cardas Golden Reference. Big difference in detail, and sound staging. The AM Excals were
bright and very detailed on the high end but lacked in bass.
The Cardas GR's toned down the bightness and opend up the bass considerably. Contact "usedcable.com" ask about the lending library. They will send a couple a pair for a 2 week in home trial. The best way to do A/B comparison.

Many people would agree with your assumption. It may be a good place to start but in the end your system and your ears will ultimately decide.

Hi
Pretty simple.
Silver is better than copper(any copper).
Gold alloy is better than silver.
Pure gold is way better than gold alloy.
Platinum blows away pure gold.
Call me if you need som platinum

good luck
