No bit errors will be introduced between your PC and your squeezebox. There are several layers of checksums that prevent this. Both TCP/IP and wifi/ethernet (they're basically the same thing bit-wise) have internal checksums. In addition to this FLAC has built-in checksums. Upgrading hard drives in theory could cause bit errors in very very rare cases, but there are good tools out there that you can use to verify copies are completed perfectly. I'm not a window user, so I'm not sure how the data validation tools I use (md5sum, rsync) translate to the windows world. The easiest thing is probably just copying the files and using flac tools to validate the internal checksums. The only real source of errors is the ripping process. If you use EAC or dbpoweramp with acuraterip enabled you're pretty safe. You're right, the only real source of "errors" in the squeezebox is the jitter "problem". Jitter happens in all spdif connections because the decoding clock and data bits are integrated. However it takes a huge amount of jitter for this to be audible. Last I remember the squeezebox jitter levels are well below audibility. There will be people that argue they can hear it but won't prove it to you. -- SuperQ ------------------------------------------------------------------------ SuperQ's Profile: http://forums.slimdevices.com/member.php?userid=2139 View this thread: http://forums.slimdevices.com/showthread.php?t=60910
