sorry bud. i know digital audio and i know how computers work. it's actually not more complicated than that.
a digital audio stream is a digital audio stream.
if you bypass the DAC and use a digital out from a CD player, every cd player is identical, barring read errors, which do not come into play until you clean your driveway with the underside of a cd and then try to play it.
snake oil salesmen will try to make you think a $100 sony player will throw a bunch of read errors due to substandard transports or some shit like that and therefore you need some expensive shit that supposedly reads the bits better but that's verifiably bullshit. capture the bitstream from the sony player and from any $500000 snakeoil, inc. bullshit player and it will be identical. it's just digital data, it's a file, it's identical.
i'm not going to try to stop you from buying an expensive cd player if it makes you happy, but digital audio does not give a shit about the price tag. it just works, the same way, every time.
