Koetsu Rosewood Signature

I bought this new from Audio Unlimited, Denver, in 2002. It was installed on a Graham 2.2 arm for about 5 years. In those years, I was splitting my time in half at a vacation residence, so the cartridge saw little use. I then bought another cartridge about 2007 after changing other components in my system, and put this away in storage in the original box as a backup. It sounded great in my system, where it fed a Nagra PLP into a pair of Manley monoblock tube amps, which in turn drove B&W Nautilus speakers. I estimate conservatively that the cartridge has no more than 500 hours, and most likely less.
