I think that is a bad combination. The Koetsu is perhaps the lowest compliance cartridge on the market. The Axiom is a lighter arm and the head shell is not what you would call a stiff design. The Axiom would be better with a cartridge in the 13 to 20 um/mN range. The Koetsu is 5 um/mN! You could add mass to the headshell but you had better have a good record clamping system. I have listened to the Coralstone version but not in that arm. It was a Kuzma 4Point 14. Nice cartridge but not the best tracker.
