The PS Audio P-300 is a fantastic device for front-end components. However, connecting both digital and analog equipment into the P-300 (when powered up simultaneously) appears to result in an edge/slight brightness in sound. I can only imagine that digital noise (emanating from the digital source) wreaks havoc with the power supply of the P-300 (or other). The two pair of outlets on the back of the P-300, to the best of my knowledge, are not isolated from one another. If digital and analog equipment are to be used together, consider a PC (or PS Audio's Ultimate Outlet?, or similar)that minimixes/reduces/eliminates digital noise from re-entering the power supply (P-300).
This is similarly true if digital components are connected directly to a wall-socket. Digital AC power noise must be minimized or eliminated for best performance/sound.
