I gave up on vinyl in the 90's and, whether it was back then or if I had an lp collection now, I'd never sell the music for equipment...other stuff, my house or my car Maybe...but not the music. I certainly recall that it took too much of my time and money to waste half of my record buying opportunities to actually wind up with half a collection that was stuff I never listened to at all anymore. If I had, that's the only condition I'd ever consider selling under, I suppose. Either that, or I wouldn't unless I knew I had a way to make backups that sounded just as good as the originals. It's all about the music. If it isn't, then I don't see why you couldn't say that you would sell your entire collection just for better gear.
