This is certainly a naive question, but why can't a CD player store the entire contents of a disc in memory, then send them to the DAC, which would be the equivalent of reading a file from a hard drive? Is that the definition of a music memory player? If it is, why is that controversial? Not spoken, of course, as a digital engineer.
Implications of Esoteric G-0Rb atomic clock
The latest TAS (March 2008) has an excellent piece by Robert Harley: a review of the Esoteric G-0Rb Master Clock Generator, with sidebars on the history and significance of jitter. This Esoteric unit employs an atomic clock (using rubidium) to take timing precision to a new level, at least for consumer gear. It's a good read, I recommend it.
If I am reading all of this correctly, I reach the following conclusions:
(1) Jitter is more important sonically than we might have thought
(2) Better jitter reduction at the A-D side of things will yield significant benefits, which means we can look forward to another of round remasters (of analog tapes) once atomic clock solutions make it into mastering labs
(3) All of the Superclocks, claims of vanishingly low jitter, reclocking DACs -- all of this stuff that's out there now, while probably heading in the right direction, still falls fall short of what's possible and needed if we are to get the best out of digital and fully realize its promise.
(4) We can expect to see atomic clocks in our future DACs and CDPs. Really?
Am I drawing the right conclusions?
