+1 For me as well… a lifetime pursuit… something constant through career changes, partners, lifestyle changes, where I lived.
I always had state of the art audio systems and a huge music library when I was out four wheel driving 12 hours a day all over the Southwest as a geologist. I had a 100 wpc system in my motel room with detachable speakers in Beatty, Elko, and Eureka Nevada…. Across Arizona, New Mexico… etc.
In airplanes I had separate earphones, DACs and amps across Europe, Asia and Mexico for decades… I collected all sorts of local music when living in Japan and Scotland. As technology advanced I had access to thousands of albums as I worked in China and Mexico… Portugal… on and on. I got some $1,000 bills in mainland China for overusing cellular data. Fortunately I was an executive by then and the company covered it.
Yeah, hobby would be somewhat of an understatement in my case. Also, to me the rewards far exceed just a hobby. I put on a Celtic album and I am swept to the North shore of Scotland where I hiked down to the water without seeing anyone for hours… and in the distance someone played the bagpipes… music triggers emotional responses back into rich experiences.
Then there has been my home systems.
