Typical audio measurement doesn't give a very complete measure of the
sound quality of *any* decent high-end equipment; responsible
designers should always use listening tests. I'm encouraged that
Philips recognized this point in their design of DCC.  But I hope they
were using analog sources along with digital ones. I'm impressed if a
DCC copy of a cd is indistinguishable from the cd; I'd be more
impressed if a DCC copy of an lp were indistinguishable from the lp;
I'd be most impressed if a mass-produced DCC made from an analog
master were indistinguishable from a mass-produced lp made from the
same master (minus surface noise, of course :).

As with everything else in audio...
