Yes, Alex, I understand your use of highly stable PSes on digital writers & elsewhere & the audible effects of its use - I was posting my thoughts on this & other similar phenomena that I have read about & my own experiences in this area. I know the usual counter-argument to the possibility of an improved digital signal waveform having any audible effect is that the digital signal goes through a number of buffers inside the D to A device so by the time the digital signal gets to the D/A chip its waveform has already been reformed probably more than once. My answer is that when an badly formed signal is processed by the receiving chip inside the DAC, it can result in common mode noise which can effect the D to A process of the signal that is currently being processed - so even though this is now a well formed signal, it is being effected by the badly formed signal at the receiving chip.
I don't see that much difference to the integrated CD player DAC where the formation of the pits on the CD could cause electrical noise while the DAC chip was processing the digital signal just read off the CD & passed through buffer. There are many things happening concurrently in a DAC device (USB input or SPDIF input) - just like there are in the CD player DAC.
