OCC copper. But there are those who make very expensive tube amps with silver wire transformers who would argue that silver is the best wire. I digress; maybe not in cartridges.
Copper, silver, or gold MC cartridge coils?
Copper coils seem to be the most popular.
Silver coils seem to have the general trait of warmer midrange and extended high frequencies, by those that prefer them.
Copper has lower mass than silver, and much less mass than gold. Better transients?
Silver has the best conductivity, followed by copper, then gold. Gold has the best corrosion durability.
Can we draw any conclusions as to the type of sonic traits and preference of each type?
Any preferences and why your choice of type, or is there no big differences sonic wise?
