it's around $50k including a phono stage.
i've spent the last 2 days here at T.H.E. Show in Costa Mesa listening to this cartridge, and it is very very good. and i own some very good other cartridges of my own, and own the Tonearm and turntable this was played on. this version of the darTZeel 'Founder' cartridge is a prototype and not the final version. they are using the internal phono of the dart preamp (which i also own).
not sure where the million number comes from. but it's wrong, wrong, wrong.
can't say it's worth $50k yet for sure, but it could be once i hear the final version with the new phono.
