Kuzma/Koetsu feedbak??

Never heard of particularly fragile Koetsu, heard something but don't remember exactly what of fragile Dynavector. 
Read about Clearaudio what lewm said.

I use a Phasemation PP-1000 on my Kuzma 4 point. Fantastic match and very underrated cartridge. Very popular in Japan and China. 

Not qualified to comment on clearaudio tts, except to say that I’m a direct- or idler-Drive guy.

I've owned a Clearaudio Master Solution from the clear acrylic episode, equipped with magnetic bearing, Synchro PSU and Unify tonearm. It was a nice looking and reliable table, but its performance was held back considerably by that tonearm. This became very 'clear' to me when it was replaced by a Kuzma Reference 313 VTA using the same cartridge (VdHul Frog at the time). That Kuzma arm was great and I'm sure the 4P will be even better.

Agree with @dsholl1 about Phasemation PP-1000. I have the P-1G (its predecessor) as well as the P-3G (now PP-300), which comes very close at about half the price. Highly recommended!

If you’re running a standard gain superline/supercap phono stage don’t go too high with the cartridge output level, the platinum magnet Keotsus are about right, the sumarium cobalt ones are getting nearer the limit but maybe not quite where you’d be looking at using the E variant but anything 0.5mV and above and you’ll be sending your phono stage in to be converted.
