People's mileage can vary, as apparently Robbob has had no trouble with his Apollo reading discs, but all that I can say is my experience was that the player is slow in starting (which I always attributed to it's buffering) and fussy with discs. It was an exasperating experience, because even after 30 seconds of silence, I couldn't be sure if that was the normal slow start or if it had rejected the disc altogether. It would frequently accept a disc if I reloaded it, but the opposite would happen as well, where it would refuse to play a disc that it had played without incident previously.
I like hassle free audio, as I am usually trying to unwind after a stress filled day, and that is my chief memory of the Apollo, getting frustrated and annoyed over these issues. Perhaps my machine was somewhat faulty and the experience is atypical, but a perusal of users forums at the time revealed that it was not an uncommon issue.
