Just to give another perspective, I've had both the 309 and IV and in both cases I compared the stock tonearm cable to an aftermarket cable (one was a Nordost Tyr and the other the top of the line Origin Live-- both about $500) and the music felt choked with the stock cable. Now I was using it on a particularly dark sound system, tubes all around and Quad ESLs so maybe the cable it just balanced well and I need something on the detailed side. Or maybe what they say about the stock cable is true. I'm sure it's a little of both.
