[playing two of these on Sansui SR636/Vincent PHO8 and Sansui FR5080/Sansui QRX6001 restored]
This seems to be a nicely made cartridge and stylus - and the stylus itself appears to be 'nude' as described and well shaped, under a low power microscope.
I initially set this to the top of the weight range indicated, for about 10 hours of playing, and then down to the recommended 1.3 grms.
At about 30-35 hours, this sounds very nice indeed - for classical records from several decades.
[Other cartridges I own: AT VM750SH, Ortofon Super OM/Shibata, Shure M91ED/Hi-Track and Vivid Line, Ortofon VMS/FineLine, Sansui SV40X/AT Shibata and Vivid Line]
