I had the JVC QLY5F for a number of years. I had a Shure Type V-MR or a designation real close to that and a high output Ortofon Moving Coil in it. I enjoyed both cartridges with a preference for for the Ort. The Shure would sail through the Telarc 1812 and track anything and was a great all-rounder. The ort had more a "whole cloth" kind of presentation that was more musical to me.
I have never had the pleasure of a Koetsu audition and I think that you could hardly go wrong with one but that is based on rep alone and you really need saddle time to see if that is the case. Check with JVC to see if compliance, mass, and other factors make the cartridge a good match for the arm. If they say it matches, hell, I would go for it in a microsecond.
Have fun!
