I've had a pair of Koetsu Rosewood Signatures either rebuilt by Koetsu ($1300 for a complete, like-new rebuild), or retipped (new stylus, some maintenance) several times by Benz Micro. That was about $800, and was also fine, but it was not a rebuild, and these things are getting old. Musical Surroundings imports both Koetsu and Benz, and can probably give you the best advice on the differences between rebuilding and retipping. Van den Hul, through Stanalog, theit distributor, also retips Koetsus, is somewhat cheaper $500? $600? and is supposed to be excellent, although I haven't yet tried them. My gut feeling is that if this is an original Koetsu from the '80s or early '90s, it probably could use a Koetsu rebuild even if that costs more.
Koetsu cartridge rebuild
I have an older Koetsu Rosewood and was wondering if anyone could recommend someone who rebuilds these things. I've never even thought of doing this before, but I see fairly often where somebody is selling a retipped or rebuilt cartridge. Any help would be greatly appreciated. Skip
