Not sure what you expect from it and what kit it would be partnered with and as sound quality is subjective then you might get many different opinions.
I had a 93eu for over a year and used it all the time for music, in all honesty with High-Res music such as SACD or high res flacs and WAV's I found it to be pretty capable... with Standard CD I thought it was a bit flat but I used an external DAC with it for that in got a really good performance.
I was trying to streamline and have less boxes though so I sold it an bought a Nuforce Extreme version of the 93 (the only difference being the analogue audio) and I am pretty happy with that all round and so even sold my DAC as standard CD now sounds pretty good too, as a one box solution like that it does a good job of most things imho, If I spent ££££'s on a dedicated CD player I am certain it would be better but thats not the point though?
But maybe the main thing is the 93 and the 95 models are about to be replaced with the 103 and 105 models, the details of the models are already on Oppo's websites and at least the 103 is due to start shipping fairly soon:
OPPO BDP-103 Blu-ray Disc Player
BDP-103EU | OPPO BD UK
PS if you are using HDMI to connect to an AV receiver then it is the receiver that is doing all the decoding too, not the Oppo.
