Critical listening at home: Audiophile High Fidelity Sound Reproducing Systems and the Recording Industry

Meet George Vardis, a retired biologist with a Master's Degree in Food Technology, residing in Athens, Greece. George is a sophisticated man with many interests, including sailing, photography, motorbikes, and music. He plays the piano and the guitar, but his career always steered well clear of the music industry. He was never a recording artist, nor was he a recording engineer. In fact, he has probably never seen a recording studio in real life.

The Mystery 

One might think that the whole issue of absolute polarity for a medium essentially invented around 130 years ago, would have been adequately discussed and standardised by now, leaving no room for further debates. Indeed, it has been, so why bother writing anything further on this topic?
