Why vinyl is kind of a miracle
Today I was listening to some vinyl records (U2, Songs of Experience). By chance, a light beam fell upon the vinyl and was reflected upon the wooden wall behind the turntable. The result was an enlarged image of the imperfect rotation of the vinyl record, and I found it quite spectacular. The miracle is, of course, that the sound that the turntable produces, is unaffected. (In this case, a newly acquired Pro-Ject Essential III, George Harrison special edition with a standard Ortofon OM10 needle).
This 'old' technology is at the top of its game, really, and even this entry level audiophile turntable easily works around substantial torque, push and pull, as can be seen in the video.
