Just remembered a question that someone here might be able to answer. What makes an arm "high mass"? Is it the overall design and actual weight of the complete tonearm? If so, are arms like the Ortofon RS309, Groovemaster and Schick considered high mass? Or can the weight of the counterweight be factored in to adapt a "normal" arm, like a Jelco, to be used satisfactorily with an SPU?
