A $20 DVD player over a $2 cable will give you a digital stream that's easily good enough to recover the bits with perfect accuracy. I know that for a fact, because I've ripped hundreds of disks on a cheap DVD-ROM drive, and all 6 billion bits or so came through correctly on nearly all the unscratched ones. So unless your source or cable is malfunctioning, there's no issue with bit accuracy. Therefore the only potential difference is clock recovery. The bits arrive at certain times (variations in those times are called jitter), and if you're interested in converting them into music played in real time (rather than saving them to a hard disk), you have to base your clock on them. But if the bit arrival times are jittery, that will introduce distortion. So one way in which DACs differ is how they deal with that issue. The Benchmark deals with it in a way that evidently renders it completely immune to input jitter. You can find details on the algorithm they use on the web if you're interested. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=84903 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
