I just turned 65 and am exploring new music on a thread on the MUSIC discussion site( "the best cds in 2011).
I love the sonics of new recordings vs. the stereo of the 60s and 70s but still enjoy the old stuff. Recently purchased Anthony & the Johnsons after hearing a track on a TV series program (House or CSI?).
That said, I plan to purchase a new audio system this year, spending $20,000+/-. I look forward to choosing the components but there are fewer and fewer brick and mortar stores to audition equipment.
The hobby is more enjoyable as I get older, not less.
