Whatever you decide (or have decided--have not read to the end of this thread) to do, DO NOT SELL YOUR VINYL! EVER. You have 1500, and therefore a good investment of titles that probably fetch over $30 each today. And while vinyl may one day be equalled by digitial, it will probably never be surpassed. It will always be a venue where some tracks "just sound better" to YOUR ears (and the same will hold true for digital).
If you have merely 20 LPs, then that’s a different ballgame, making a hefty investment in vinyl debatable.
If I were you and had 1500 LPs, I would have BOTH a superb turntable AND DAC/Streamer. Just skip a year or two going to Europe. Or sell that third condo. You know? ;)
Some have suggested a "vinyl-centric" system for you. Yes, a great path. But I've been bitten by the convenience of streaming and the gap between digital and analogy (vinyl) is getting so close that the enjoyment begins to fade every time you have to get up off your ars and change an album just because you only want to hear a few tracks.
Again--DO BOTH. Without compromise. My two cents.
