"...rarely are things discussed like wow, rumble, resonance, compliance, etc. Why is this? Why aren’t vinyl/analog setups discussed in terms of physical measurements very often?"
I disagree. These features and specifications are very often discussed here in these threads. I would bet that most, if not all, vinyl enthisiasts here pay very close attention to the measurable aspects for cartridges, arms and turntables when making not only decisions as to what to buy, but what to listen to before purchasing.
Do you have a specific question about any piece of equipment you're interested in?
