Most decent external DACs and preamps have a Dejitter circuit. Basically a small memory to store the stream as it arrives (just like a computer capture device). It then pumps that buffer out on a new clock for internal use (e.g. a DAC). That is, it records it to storage and the plays it in real time. So yes, I have not proven some crappy receiver won't screw it up. But I have shown the data can be captured without error and if EMU 0404 can do it I expect a quality preamp/DAC can to do as well and if can't, get one that does. The EMU didn't use any special external word clock.
People think SPDIF has to processed immediately to the DAC as it arrives. It doesn't. That how DTS, AC3, work. SPDIF is just a transmission medium and it doesn't have to directly drive your DAC clock. It can be buffered and often is and the SPDIF is just a transmission medium and as long as like you said they arrive in order with correct values then it's the consuming device that should reclock it and be responsible for timing of it. And that's how most equipment is these days. There is no need to make the bits any "squarer" if they are already good enough. Like I said earlier since my system does reclock it (several times). I plan to check it further down the pipe as well which will confirm the prior stage got it right. Like you said it does not matter until you get to the DAC, but the DACs in some cases are a long long ways away. In my case they are AFTER the crossovers in the speakers. My assumption is if folks are serious enough to think about Mods and external word clocks for their SqueezeBox I would hope they have a dejitter circuit somewhere very close to there DAC. -- mswlogo ------------------------------------------------------------------------ mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=34292 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
