Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

Thanks again

I'm amazed that switching clocks does not cause a glitch on the 27MHz line. Good on you, bet that took some effort to get right!

I seem to recall you are also using an upsampling filter. Is that true? If not, then presumably you need to buffer the audio signal from the MPEG decoder to filter out the jitter?

If you are (using upsampling), did you consider using ASRC on everything to a single common rate (eg. 200kHz)?

There's been a thread recently that the Lavry DA10 does this (even though the user manual suggests otherwise). Everything is resampled to 115kHz - I was wondering why Dan chose such a low frequency (since that would mean 192kHz gets downsampled), then I realised he's trying to force the DAC into dual rate mode.
