If you're willing to put up with the added complication of a Proceed PAV/PDSD combination, you can have 5 channels of XLR outputs to your amps. The Proceed PAV accepts XLR from CD/SACD and AUX inputs, and has analog pass-through cability. I have four boxes between the sources and the speakers, PAV, PDSD, Amp 2 and Amp 3. The PAV and PDSD communicate via a special port, so the PDSD could be hidden away, given that it has no knobs or displays. All control is by way of the PAV and its comprehensive remote. The PDSD output to the amps is via 5 XLR lines.
