Please be gentle, I'm a noob with this sort of thing!
Anyways, I was doing some spring cleaning today and came across some old audio equipment my parents inherited from my grandfather. The stuff has been sitting in a closet for years, but he had a reputation for having expensive taste. Turns out there's an old JVC xl-m409 cd player, manufactured in Tokyo and individually serial numbered, and I was curious about the built in DAC. I'd heard stories about really superb quality DACs being used in these Japanese electronics in the mid 90's (manufacture date on this one is 1993) and I was wondering if this was worth anything or not.
I googled the model number and found virtually nothing, so I cracked open the case to peek inside...problem is I don't really know enough to do anything other than google the part numbers on the chips. Any help would be appreciated! If you need a closeup of a specific area or more info I can get it, but attached are a few basic pics. I certainly don't expect you to be able to read serial numbers but if somebody can circle a specific place to look for info I can get back with it.
BTW I spotted several of what I believe to be 4580D opamps.
pics are big so I just linked them

junk or newly found treasure?
