OmeEd,
I think that vacuum tube amplifiers in the right playback systems do have Aesthetic properties, and more importantly when playing music, they can open doors to enhancing spiritual experiences.
As an analog and hardware person, and experience in calibrated measurements since 1959, I still find it hard to measure Aesthetics, Mysticism, and Spirituality.
I was only aware of the Camera Obscura and pinhole "lens".
I did not know about glass lenses or other material lenses written about in 423BC.
I gave my Hasselblad 503C to my granddaughter.
