In keeping with what Dover infers about quality control at Koetsu, I purchased two Urushi, Wajima version, over the counter in person from a dealer in Tokyo, with my son acting as translator. When I got back to the US, I found that the cantilever of one of them was deviated to one side very noticeably. I returned the cartridge with proof of purchase and the Japanese warranty, and within a very short time I received a replacement that was perfectly aligned, at no charge even for shipping to the US. So, although Dover has a point in my opinion, it is also true that Koetsu will stand by their product. I would only hope that the US distributor would do as well for cartridges purchased in the US.
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?
