Fatparrot...You may like vinyl for whatever reason, but the notion that signal-to-noise and separation is better than digital is flat out wrong. Very wrong.
There is no straightforward way to calculate signal to noise of vinyl, but a few minutes of listening makes it clear that the analog signal, whatever its virtues, is accompanied by noise. Some LPs more than others, but it is always there. Some people (like you) can "listen through" the noise. That is a talent I never perfected.
The standard LP mastering process blends stereo signals below about 150 Hz, to avoid inherent tracking problems with vertically modulated grooves. Also, many people find a rumble filter to be necessary, and the best of these blend (rather than attenuate) LF signals. Above this LF range, I suggest that you review the separation specs of phono pickups. 25-35 dB is about as good as it gets. Actually, this is not a big problem. After all, the sound from two loudspeakers is not well separated. For that you need headphones.
It's interesting that people who reject DVD-A and SACD say that there are no discs that are any good. How would you know? You were correct once, but good discs are coming fast now.
