Music, listening and trying to make it. Literature... a lot of things. Life is long and curiosity is a strong force.
A large list. Too large indeed.
Headphone Amp Inventory:
A large list too. SE, balanced, for electrostatics...
More than 4 audio sources.
One of the silliest things I've spent too much money in my life.
I even spent money on these too.
Other Audio Equipment:
Speakers, amplifiers, more cables...
None worth mentioning.
Jazz in almost all its forms, but specially hardbop, bebop, swing and vocalese, from big bands to solo acts.
Classical: almost everything but large orchestral works from XVIIth century to mid XXth is what rocks my boat. Anything Beethoven.
Prog rock, classic rock, hard rock, blues, pop, soul, r&b... I like almost all music but too idiosyncratic "world", folk, most flamenco and teens pop. I don't get most electronic, drum and bass and hip-hop.
