Cartridge upgrade

Hi all.  I have a quick question.  I have a Marantz TT-15S1 turntable that I've been enjoying for the last couple of years.  I am still using the included MM Clearaudio Virtuoso wood cartridge that has served me well so far.  At the end of last year, I upgraded my phono stage to a Manley Chinook that I like a lot.  I am looking to upgrade my cartridge this fall.  I was looking at Kiseki Purple Heart NS.  My question is this, does it make sense to put a $3,400 cartridge on a $1,700 (base audiophile) table?  I imagine there will be some sound improvement but how much?
