I won’t say my quad LP collection is any better than anyone else’s here, but it’s reasonable at least. I don’t have an inventory of the quads because I don’t really have an inventory of my vinyl, so it’s hard to say just what’s in there or not.
I’ve been putting a lot of digital stuff on discogs, and it and my 7” collection are there, along with the Franklin Mint classical collection. Next will be the 78rpm stuff, then the LPs. It’s very time-consuming to put a new release up there, so putting 1300 or so LPs won’t be done any time soon, as I expect about 20% of my collection will end up being my own new submissions.
Of course, I haven’t been able to play vinyl for five or six years, although I have both a surround master and a CD-4 decoder, one of those relay switches, surface noise reduction and a dbx decoder, but sadly, none of it is hooked up and none of it has been powered up since I moved to Idaho. (One of my turntables was damaged in the move and not discovered for two years while it was in storage, the other needs a bit of attention that has been given to other projects.)
I noted in another thread that I’m actively shopping for a turntable that can play CD-4s, but so far I’m not attracting the attention of the local shops, in spite of my waving around a nicely funded budget.
