Well, you've left half of it out.  The Phillips method, which uses
a 14 bit D/A, also does some digital processing that's been discussed
at least 15 times here that ups the sampling rate by 4, thus spreading
the noise out over four times the bandwidth.  The sigal, however, is
NOT spread out by this process.  A little preemphasis/deemphaiss built
into the various filters, and  you have the same SNR, except that the
Phillips is linear phase, and the Sony isn't.
