Okay, so would that be an endorsement of the Oppo 205 as a transport?
Amir's tests really have not shed any light on optical transports, pun, pun! But, I don't think you can go wrong with an Oppo, any model. But, frankly, others may be just as good as transports. It is the DAC and audio circuitry that really sets the 205 apart, although Oppo has also always had benchmark performance on video as well. I have had a number of Oppos over many years, and I always found them excellent, though I never had a 203/205.
However, I play all my files either as ripped from PC hard drive or as played by the cheap optical drives in my PC. I have detected no noticeable audio or video differences from using a separate player as a transport vs. the internal PC optical drives. But, I find file audio playback from hard drive subjectively a bit more "relaxed" sounding, meaning slightly preferable, but nothing to get excited about. No noticeable difference on video quality, though. There is speculation in some circles that servo motors and the electromechanical optical drive assemblies might slightly modulate power supplies or generate slight variable EMI internally, more so than with PC hard drives. But, that might also be a total myth.
I think it might be fair to say that no measurement studies have indicated anything significant about most optical drives in PCs vs. separate players or confirmed the superiority of hard drive playback.
Note also that use of an Oppo as a transport might restrict player output options, such as with SACD, due to DRM. No issues with CD, however.
