I think my comment was valid 5 years ago (or more?) with the Cambridge Azur 650BD/651BD and I haven't looked into it since because of the Sony UDP-X800 (which came out in 2017?)There isn't a single currently available Cambridge component that even remotely compares to any Oppo player. The only thing that comes close is the discontinued CXUHD, which is a universal player like the Oppo, and uses the same Mediatek platform, but the CXUHD doesn't contain any DAC onboard. It is a disc transport only.
So, exactly which Cambridge component is a "rebadged" Oppo?
