I have been using the SME M2-12. Previously I had used the 3012 S2 (not 3012R). The M2-12 is a much more superior tonearm compared to the regular 3012. The M2-12 has a much higher dynamic range and resolution. It actually mates rightfully with the new age modern cartridges without limiting their performance. The 3012 always had a vintage sound whichever cart you put in, somewhat veiled, slow and lack in inner detail. Where the 3012 excel is in the way music flows, that flow is terrific and is a reference for any tonearm to compare. Just like the flow of vintage turntables this tonearm also has that magic. In the end though it is not a candidate to be used in a high resolution setup, while the Schick and M2-12/12R do not have that limitation.
I would love to hear the 3012R some day.
