Hi Richard,
ATRAC3 indeed provides a greater compression ratio, about double that of the
original ATRAC. Sony claims better integration with equipments that also
use ATRAC.
Sound quality is supposed to be "MD-like". I'm assuming this means slightly
inferior to MD depending on the source. The reason for such assumption is
that the first MD equipments were said to be "CD-like".
ATRAC3 first surfaced with Sony's memory stick walkman last year. In this
case, ATRAC3 is available in three compression ratios: 132kbps, 105kbps,
and 66kbps. 105 is the "standard". I'm not sure what ratios are used on the
new MD equipments.
