What are you talking about?

Seriously, ok, it is as you say, but as you know, in the last 20 years there has been this discussion about measurements vs. experienced sound quality. There are some distorsion that is audible, some that is not and yet some that sound good and so on.
Many audiofiles still play 12 inch vinyl disc on a platter driven by a motor via a rubber cord. The low level signal is then heavily equalised and amplified.
How do you think this measures?
