Hi Bob,

        I can't help you with P-bus, but I'm just curious, wich storage device
do you use ? FlashDisk ?
        I'd like to set up a similar system, since you've already been there...
        Is the overall sound quality good ?
        Wich sample rate you rip your CD's ? 320K/s MPEG1 Layer3 ?
        My idea was to interface a 20x4 LCD with LED backlit serialy (With a PIC
to stay not so OT)
to the Linux box and control via a custom keypad, but your idea to use the
Pionner sounds cleaner.Hmmmm.
        Did you already tried to analyze the signal ?
