Not a hobby for me. I like listening to music. ROON says 218 hours in the last 4 weeks which is likely lower than normal since I took a week off from work and I was entertaining house guests for the past 2 weeks. I also have 3 hours a day M-to-F of bliss listening to KCRW morning show on FM radio (not included in ROON).
I think it was Ozzy Osbourne who best described my gear spending habit. I was a zero for a decade and became a hero in the last 3 years. In about 6 more months I expect to go from hero to back to zero for a very long time (maybe until the end).
