Forgive me for side-stepping the question, but I think it would be pointless to guess without making some quantitative measurements on the electrical output from a typical Toslink receiver module. That said, I have made a couple of observations which may be relevant: - if you look at the end of a Toslink cable, the light coming out of it is fairly omnidirectional; there is no particular angle at which it suddenly looks much brighter than others. Therefore, it's unlikely that a misalignment of a degree or so would make much difference. - an opto-isolator designed to pass data at a couple of Mbits typically has rather slow rising edges on its output, because of the passive pull-up used to bring the output to a logic '1' in the absence of light from the LED. This would inherently tend to increase jitter - and a Toslink connection is basically just an opto-isolator with a particularly wide separation between the two halves. I will be looking into this properly in the not-too-distant future, so I'll post my findings if anyone's really bothered. -- AndyC_772 ------------------------------------------------------------------------ AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=33146 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
