Some more investigative work over several weekends by swapping power supply modules. Found the culprit: the Salas UBiB supplying to the 5V digital rails was probably dipping below the acceptable level as it warms up. I increased it ever slightly above 5V and it has been stable ever since. Put back Edward's audio improvement scripts and all is good. For those who have not tried it, don't wait anymore. ;-)
