Oh wow. That is uncolored. We can probably end the thread now if we want.Here is another graph of the VM540ML, from the LowBeats review:
Unfortunately, I don't see any notes on what loading they used.
I found a possible downside of the plastic body of the VM 5-series:
My grounding wire came undone and I got not only hum (expected), but also buzzing (first time).
I haven't had buzzing with any of my other carts (most of which have metal bodies), so the claim from AT that 7-series metal body adds extra electromagnetic shielding may be true.
Re-attaching the grounding wire made both the hum and buzz go away, or at least at normal gain settings; I didn't crank the gain to check.
Interesting thought about shielding. I assumed the only difference was that gold-toned Al looks cooler. I guess those wires can need some pinching. Pretty sure the tonearm wires are directional due to slightly bigger ends on one side. Not sure if you looked at that.
