Music lover with a broad taste - from AC-DC, Aimee Mann, Beethoven, Leonard Cohen, George Harrison, Heilung, Laid Back all the way to The Who (and sometimes even Rammstein).
Audio & Hi-Fi: crusader against charlatans selling snake-oil and 1000$ spikes, cables and gadgets - fake news and fake stuff.
I highly recommend the Music & Audio bible, by Dr. Mark Waldrep (https://www.musicandaudioguide.com/).
