I'll have to refer to the specs later,...
but I'm pretty sure all the consumer Sony MD recorders, full size components, have 24 bit A/D-D/A's, which then goes through the ATRAC data compression, and then to MD in the ATRAC format.
Like I said, I'll check the specs later, about the 24-bit front A/d-D/A's.
Anyway, I haven't had time to look this up either, but will later, and that is,... what's the front end A/D-D/A's on the 564? Hmmm? I'll look it up later. C'ya.
Agreed, MD is not suitable for 'full-pro' work, since the bulk of the professional recording world is 24/96-uncompressed recording, but MD is a good digital format, nonetheless. It's targeted for the mid-level digital market, and it's a heck of a lot better than cassette. MD is good for read/write digital in the studio or the field, but it's not 'pro-format'.
I think the debate on whether the compression affects the sound or not, will go on for ever. For what it's worth, I've never heard anything wrong with MD digital recording in ATRAC format, and you can quote mathematical formulas all you want, but IMO, whatever difference there is, you may be able to calculate it, or display it on a scope, but the differences would be well below the threshold of human hearing. I just think people 'think' they're hearing a difference, because they 'should'. In other words, I think it's a psycho-acoustic placebo effect, or plainly, people are fooling themselves. Anyway, that's my 2c.
I'm in the computer industry, and data compression is used all the time, and it never harms the data. How do you think they get 80 Gig of data on one little reel of tape, that will fit in the palm of your hand? The data always uncompresses normally, and IMO, so does the ATRAC/MD data.
Okay, now that's 4c worth of opinion.
