I've owned both the SME V and IV.Vi tonearms, but had the V when it used to be wired with Vdh copper and not the Vdh mono crystal silver which it is currently wired with. To my ears, the IV.Vi's Magnan copper wire sounded more extended at the top and better balanced overall than the V's Vdh copper wire. I have not heard what the V sounds like with its current Vdh silver wiring, however I recently had SME rewire my IV.Vi with silver Audio Note wire, which I hear as more organic sounding and somewhat better balanced than the Magnan copper. Nevertheless, I agree with Cjfbrw's comment about the influence imparted by one's table, cartridge and amplification chain. Of great importance also are the subjective preferences of the listener.
