I have one.
It's an amazing cartridge and competes in the 2k category in my opinion. Another forum owner, on hearing mine, declared that it would retail at £2.5k if made by one of the smaller manufacturers.
It is an unusual cartridge though as it tracks at 1.3g or under so definitely worth checking tonearm compatibility. It has a ruler flat response so it can appear "dull" on first listening but it has an ability to dredge detail from the groove like very few others.
Those who consider it a modified DL304 are profoundly wrong. It has a much finer diamond and different coils.
