As a cd mech ages its ability to accurately track a disc does become gradually impaired. This gives rise read errors. The disc play perfectly on other mechs but because of the CD manufacturing tolerances, particular combos of discs/mechs will give more errors.
Also, dirt build-up on the laser will increase read errors. By the way, interpolation "CU" is happening a lot more often than you might think. Those early players (which had great mechs) that had error counters (showing both correctable and uncorrectable errors) were apparently unpopular with the public because they put out the wrong vibe..."perfect sound forever" didn't sit well with a read error counter racking up the read errors. Even new discs on new mechs can give (interpolatable C2) read errors. An accurate DAE rip of a given disc is going to be as accurate as you can get for a given disc. The SPDIF stream will rarely be bit-accurate by comparison, IMHO. You might find this link interesting (and yes I know it doesn't address the central question...I'd like to have seen what happened playing a normal undamaged CD...) http://www.digital-recordings.com/ded/sensnd01.html -- Phil Leigh ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=24957 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
