All my classical music is on vinyl, as is most of the rest, and hasn't been played for more than a decade as my HiFi system hasn't been in use for this length of time. Main problem, my Sugden's A48 amp needs repairing (one channel down), I probably need a new stylus for my Planar 3, and the speakers need new cones (having tears in at least one). The whole is still worth resurrecting though if I wasn't playing mostly ripped mp3s, hence little classical music listened to now apart from via TV and radio or occasionally via the internet.
Apart from organ music I can't say I have any particular favourites although early music I quite like - the instruments then and dance music.
I do have many CDs and cassettes too, but likewise, they rarely see the light of day much either.
