I go record "shopping" in my own stacks I haven’t been through for years. The last several years I’ve been on a hard rock thing- not "classic" rock, but post-psych, pre-prog, proto metal. I’m now dipping back into my classical records (old EMI ASDs, Deccas, Londons), and I have taken an interest in so-called "spiritual jazz" which is a nice change from the usual warhorses.
I’d rather have quality over quantity, but something to be said for tens of thousands of records to browse through if you have the space. Not sure I’d go out today with that goal in mind, my pile was the accumulation of decades.
