I have an older 507. So I was interested to see if there are really any major differences between the two. I couldn't find anything significant, really technical. Different head shell, cables, wiring, type, plaque, that's about it. Dynavector site states that it is lighter, smaller, but dimensions and weights are exactly the same, and they don't make it clear what they refer to - 501, 505, 507? Am I wrong, or is it exactly the same arm with mostly cosmetic updates and a hefty price increase? The only difference I could find architecturally is a slightly shorter and wider arm-lift cylinder, with subsequent machining necessary on arm base...
