Since the Yggy is $2300 - it really should sound better.
Comparing it to something in a similar "snack bracket" - I found my Schiit Bifrost, with the 4490 upgrade, was not as good as the Node 2, which provided much better imaging and reproduction of delicate venue acoustics.
I stream music directly from my NAS drive, but I am still to try the various streaming services.
Can’t comment on the Oppo, never owned one - sorry
Regards...
