hi dvb:
you made an interesting comment about the sacd medium, when you mentioned "all things being equal".
do you therefore acknowledge that given the population of sacd players, it may be possible to achieve better sound from the hybrid layer when using a particular redbook player or dac/transport combination ?
for example, my favorite cd playing device is the original zanden dac.
it may be possible that the zanden, with a suitable transport could produce better sound than an sacd disc with an sacd player.
i realize "better" is subjective, but perhaps, some redbook digital hardware can exceed the quality obtainable from an sacd disc.
