Cartridge upgrade


Dec 29, 2020
I’m planning for a potential cartridge upgrade and I wonder if someone would have any experience with the Koetsu Rosewood Signature Platinum used with a Kuzma 4Point 9 tonearm? From what I’ve heard all Koetsus (and the non-stone versions in particular) prefer heavier mass tonearms. The Kuzma 4Point 9 tonearm has an effective mass of 13g (which means it isn't that heavy). I also understand that the weight of the Koetsu Rosewood Signature Platinum isn’t 9g as most web sites seem to say, it’s supposed to be 12,8g. Are there other “comparable” cartridges that you believe would fit the Kuzma 4Point 9 tonearm better than the Koetsu Rosewood Signature Platinum?
I currently use a koetsu wajima on a triplanar se tonearm which sounds very detailed, clean and a good match. In a previous life, before my thieving ex-wife sold most of my system whilst I was working in the Middle East, had a koetsu blue lace on an earlier version triplanar which I wish I still had.
not familiar with your tonearm unfortunately, but good luck with your final selection
Other makers will come and go, charge ever increasing prices but I’ll just stay with koetsu
