I'm a little late in joining this discussion but I think what Onhwy61 said about distortion is absolutely correct. Call it what it is. Tube equipment adds it and I suspect a piece of equipment could be designed that would emulate tape saturation and/or vinyl compression even more accurately. Perhaps a business opportunity exists here. This would not compensate for bad recording technique or bad pressings but in the case of a good CD recording, would provide what vinyl lovers would call "magic".
I can remember the digitally recorded vinyl records from the late 70's, early 80's. They seemed unbelievably good. I also have a compilation CD of Asian music where I swear that one of the tracks came from vinyl. It has the sound of vinyl complete with the ticks and the sense of space and immersion is undeniable. I will agree that vinyl does offer a very pleasant listening experience but I would dispute the assertion that digital is an inferior medium.
