The custom firmware that I have installed on my Oppo 105 has the ability to play ISO images of SACD discs. Would this give any audio benefits as opposed to playing the physical SACD disc? I know very little about jitter, but would playing the mounted ISO reduce the jitter factor? I’ve always felt that the Oppo sounded slightly on the bright side. Is this what jitter sounds like?
Jitter can sound a little bright (as well as a lot of other things.)
With an ISO you’ll be saving the noise from the transport motor and the head mechanism, so there’s a chance that you’d get cleaner sound.
