If you like folk/bluegrass/acoustic stuff, Chris Thile is definitely an audiophile in addition to a virtuoso musician. Nickel Creek’s album A Dotted Line is impressive on any decent system. His other projects: Goat Rodeo, Punch Brothers, and duets with Edgar Meyer, are all equally impressive. I’m a sucker for acoustic strings on good speakers, though.

My Gen 1 Heresy with a Philips head looks like junk, but I’d lose my mind if I found them at a thrift store.
