I got back in to vinyl heavily about 4 years ago and I've accumulated833 (per my discogs collection).
Frankly I've never wanted to own so many records that I didn't listen to many of them and didn't even know what I own. So I've tried to curate my buying to only records I truly really like or love, purely on the music (not "collecting" records just to have them, no desire to "complete" sets or anything). The result is that I have a good idea of what's in my collection and I can grab any album and enjoy it.
Still, it is addictive and I have to get a lid on purchasing or I WILL become one of those with "too many " records. I think sheer ergonomics and space for records may put a cap on mine around 1,000.
