Ntscdan, sorry for my lack of clarity earlier. What I intended to say was that you can't draw any meaningful conclusions about the overall quality of digital vs. vinyl by comparing any given CD to its vinyl counterpart. Obviously, you could make a comparison and determine in any individual case which version you prefer.
I'm not at all surprised that you could prefer your own vinyl to CD conversions to commercial copies. I've converted a large part of my vinyl collection to digital and came to roughly the same conclusion. Surprisingly, I also found that about 30% of converted music actually sounded better in digital than the original vinyl. Heavily processed rock and pop took to the conversion best.
