Mark, good job assembling a pleasing rig!
Give some serious consideration to working with the CA amps in Mono mode. Superior results when Mono and biwired. The 803D should be beautiful with these amps in single Mono mode; the 803D is 90dB sens. and 8 Ohm nominal impedance - just about ideal for Mono mode on the amps. I don't mean biamp mono, but single mono at about 800wpc. See the Owner's Manual if you are unsure of what I'm discussing.
I wrote a review of these amps for Dagogo.com, own two of them, and use them in Mono mode whenever possible. So feel free to contact me about it.
