The Grado Prestige Black is better than the OM 30 so I think a Grado Gold would obviously be better.
Grado Prestige Gold or Ortofon OM 30 Super
I have a trusty Systemdek 2x with the stock Profile arm and contemplating whether to get a Grado Gold or an Ortofon OM30. My setup leans towards the warm side of the musical spectrum and I listen almost exclusively to acoustic jazz (ocassionally some fusion): PS Audio 5.6 preamp, PS Audio Delta 100, Esoteric D500 Transport, Assemblage 2.0 DAC, and Mirage OM7 speakers; interconnects are Cardas Quadlink 5c's, Cardas Lightning Digital Cable and Kimber 8tc in double runs for biwire. Any recommendations out there would be appreciated.
