Well ... I have a Grado Reference (1500 price) on my turntable Project 6Perspex ... I ordered this cell to test its quality compared to my Grado (which is 2 and a half times the price it is on). I have an amp that accepts RIAA MM.Du sudden curiosity tempted me to test it! Ben must not dream .... the Ortofon is a thousand miles behind .... serious clumsy medium ... OK but the highs are clenched, lifeless ... no pleasure in listening! Maybe compared to models of its price class excels but frankly I owned best cell for 400
