I guess about 1000, 25% jazz, 25% classical and 50% rock. I started buying LPs in 1973, fell for CD's "perfect sound forever in 1987, but have come back to vinyl.
Most of my buying is used, ungraded, at a local record show that takes place quarterly. I rarely miss this show, and usually spend about $100 each time. At an average of $2/LP, I add about 200 LPs per year. I have learned the hard way to carefully inspect the used LPs I buy, and more recently to make sure the cuffs match the collars (i.e., the LP matches the jacket). But I have made some great buys: This show is for 50s and 60s rock fans. If you find someone selling jazz or classical, they are usually eager to blow it out for $1 or so per LP. This past Sunday I went to this show and really made out well - a DG 45 rpm classical LP for $1 and a beautiful Capital Stereo recording of Shostakovich's 11th on a 2-LP set - paid a bit more for this one.
I am slowly, slowly, digitizing them onto CD-R for use in the car, and then ripping those CD-Rs to my music server. No, the digitized LPs don't sound as good as the original vinyl, but they blow away most of the commercial CDs of the same albums. Especially in dynamics.
About three nights a week, I unwind after work by listening to one of the hundreds of LPs I haven't heard yet. Healthier than supper or a cocktail, and even more relaxing. It's thrilling to find out if the LPs, whether they look good or not, sound good. Interestlingly, I have found many thin LPs, like the RCA Dynagrooves, that sound better to me than some older heavy-vinyl LPs. I guess then, as now, it's about the recording, the engineer and the mastering as much as it is about the quality of the vinyl and the pressing.
My KAB EV-1 record cleaning machine has paid for itself many times over. It takes filthy dirty records and makes them almost like new.
Will I get to hear every LP, digitize it, and rip it to my server before I drop dead? I dunno, maybe not. But there is the thrill of finding a treasure among the trash, buying it for a buck or two (especially when new audiophile LPs are selling for $50+ a pop) and looking forward to that first time it gets onto the turntable.
Storage has become an issue. My wife, who rarely complains about my hobby, the money I spend on it or the space it occupies in my basement man cave, has begun to show her irritation at the space occupied by my growing LP collection. I am hoping that, as my kids leave the nest, I will have a bit more space to store my LPs. But even though every time I go to a record show, with an oath to focus on quality over quantity, I always seem to come home with another stack o' wax.
Hey - everybody needs a hobby!
