Might sound like a backward step, but the Ortofon SPU Royal N is pure musical magic, I know people that have replaced Kondo IOM's with it and have not looked back. It does need quite a massy arm with VTA adjustment and a phono stage with a decent amount of gain plus a minimum of 100ohms impedance. People may wonder why not the full SPU version, 2 reasons it sounds better and costs less.
I don't know if you guys have heard if Living Voice speakers from the UK, if not check out the website. Anyway the guy who is the mastermind behind Living Voice, the SPU Royal N is his favourite cartridge, above all other cartridges whether they be Kondo's, Fuuga, the top Ortofons, Van Den Huls, Lyra's et all.
Anyone reading this with whose interest has been pricked, give it a punt.
