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.

Comparing turntables in different systems..
Table is a 'pace maker', the beginning, it sets things in motion, gives the drive and propulsion. Any decent cartridge would do, you should still be able to hear and feel what the table does even if the rest of the chain is not much to write home about. Just ask dealers to keep it quiet with their great ideas and incredible knowledge. This is a very serious buy, and I don't mean the cost. If the table is not satisfactory the entire system is not satisfactory. Kuzma is popular among those in the know but it must sound great to you.
Albert Porter is one of very few people whom I listen to when it comes to audio, turntables or not. He uses highly customized Technics direct drive, before that he used top Walker, and before that I think SME. 

Nothing against or for Kuzma but I think that at this level you might want to compare a few turntables, preferably in the same system. Especially if you are going to keep your analog front end for a long time. It is usually difficult to arrange this, I know.
Turntables/tonearms do not sound the same, in other words they do coloration differently. Cartridge is least important, Koetsu or Airtight, almost non-issue if you want to go in this direction.
