I can't fathom how anyone can watch a feature length film on a fifteen inch screen. It's all the more unfathomable when you add high quality sound to the equation.

Hello,
the bottle neck in the Prime System is the PPS USB cable. Change the cable, please. I use the Audioquest Coffee between the PHA and the computer AND(!) between the PHA and the PPS.
I've asked Meridian why they deliver with the Prime Power Supply (PPS) an USB cable from Explorer. The audio quality level of the DACs is very different. They answered that the cable is to let the customers to TRY(!) the PPS as soon as possible. Later on they can choose a cable that they prefere :) And belive me you would prefere...
