Been searching for where I read it, but can't find it now. Anyway, what I read was someone saying that the phase response of vinyl was superb, and much better than digital. Does anyone here know if this is indeed the case, why that would be, and what the possible effects of that would be on perceived sound quality? Could it account for why so many people still prefer the sound of vinyl?
Sometimes I hear people say that vinyl has great phase response because the RIAA encode and decode are conjugates of one another, i.e. the phase-shift of the cutters EQ is cancelled by the opposite one in the playback decode. Which is great in theory, but no two cutters have the same encode curve as it's adjusted, one way or another, to be flat on the particular system and does not look exactly like the textbook RIAA decode curve.
In the olden days, magazines would publish pictures of the squarewave response of cartridges from a test record (the record actually has a triangle wave cut on it, but that's a story for another day) and some looked pretty good. Faithful squarewave always means good phase response.
I think those tests were at 1kHz, but PG could verify that value and I'm sure add much more to the discussion.
Although I think it's safe to say that well-implemented digital beats vinyl in every _measured_ parameter.
