Over a decade ago I had the P5. It is NOT a balanced design, although as I recall, the XLRs are separate from the main boards. I eventually got the P6, a significant upgrade, but that went down the road too. For the last 4+ years my Audio Alchemy DDP-1 pre/dac has served me very well. Ive made wholesale changes to the rest of my system, the DDP-1 passes them all through. Great value if you can find one; the outboard PS is a must
