Immedia RPM-2 tonearm
If the sole criterion for choosing a winner in today's hotly contested premium arms race was original thinking, the Immedia RPM-2 might well come out on top. While some of its design details resemble those found on other products, in many significant areas the arm is unique—not for uniqueness's sake, but in order to efficiently implement some clearly considered goals. If the unipivot RPM-2 bears a resemblance to any other contemporary arm, it is Naim's highly regarded ARO—which I've never heard. The similarity, though, would appear to be superficial.
