I have no personal nostalgia when it comes to vinyl. I was born in the early '80s, and I never saw my parents play a record (my father had a turntable, but it was in storage; my mother mostly listened to what my father listened to, which was '50s-60s oldies on the radio). My own personal listening devices were a Walkman and a Sony AM/FM/cassette boombox. In the early '90s, I asked for a CD boombox for Christmas, and received one along with a CD (The Beatles 1967-1970). I marveled at the improvement in sound quality and ease-of-use over cassettes.
Ironically, it was this which triggered a curiosity in me regarding the flat disc-shaped format which had preceded the CD. Well, that and seeing a picture of a Wurlitzer 1015 jukebox replica in a novelties catalog. I couldn't afford a jukebox, nor did I have the room for one, but I decided to see about getting myself some sort of record player. We had a couple of Emerson tabletop AM/FM/phono/8-track stereos in storage, and a bunch of records in the attic. Neither of said stereos worked very well, and the records weren't in great shape, but I became allured by the crackly sounds they made when being played, as well as how they looked as they spun while the music was playing.
As time went on, I got an additional Emerson tabletop stereo (this time with a (broken) cassette player instead of the 8-track, and a somewhat newer/better BSR record changer on top) which worked a little better, but I started to desire an actual stereo system. I asked for a Radio Shack stereo receiver for Christmas, and received one (an Optimus STA-300). My father dug his old turntable and cassette deck out of storage, and helped me buy a pair of Optimus full-range bookshelf speakers at the local Radio Shack. Over time, my meager collection of records grew, and at some point, it turned from a novelty into a full-blown interest in the sound quality of records.
I slowly began to upgrade the components of the stereo, replacing the Optimus receiver with a used Sony, and eventually inheriting the rest of my father's stereo system (Sansui integrated amp, Kenwood tuner, and Kenwood speakers). I started finding records at yard sales, and widening my interests in music. Within a few years, I discovered the world of vacuum tube audio, and with a turntable at the helm, built up my stereo system even further. So really, I'm in this hobby because of vinyl records, and will likely continue to be so because of them as well. I have digital music players, and have ripped some of my LPs to MP3 for listening in the car, but when it comes to sitting down and listening to music, it's vinyl all the way.
