I'm definitely more of a fan of pbthal vinyl rips than Dr. Ebbetts, whose rips tend to be far too bright. Pbthal's are still very clear and detailed, but not artificially so. I discovered recently that I have 97 albums (26.7GB!) of his releases, and that's just a small portion of what he puts out! What's interesting is that, especially recently, his rips have consistently outperformed any available CD release of the same album, including MoFi releases. Each of his Pink Floyd, Rush, and Yes rips are superior to any digital counterpart I've heard. I've ABXed each of these before coming to that conclusion. Some are tough to distinguish, but sometimes little moments are where his rips shine, like any orchestral bits on Pink Floyd's - The Wall, which is an otherwise good MFSL pressing. If you want them, you have to track them down, since providing links is a no-no. Worth the effort, though. Just stick to albums you already own in some other form to keep it ethical.
As far as album that don't have vinyl counterparts but are excellent, a couple that always come to mind are Chroma Key - Graveyard Mountain Home, Bjork - Debut, and Dire Straits - On Every Street. Gooood stuff!
