Thanks to all!
Internetmin: You were right, the load dips and a that requires a lot of transient capacitance. I found out what that term meant and then pretended I knew all along.
I talked with a dude at Emotiva and we concluded that the XPR-5 does the job - transient capacitance 180,000 uF.

It also has lots of Holmes and Watson (600 @ 4 ohms x 5 channels).
I was cautioned that this amp requires a 20 amp line - can anyone educate me on that? I suspect it's not just that funky socket?
Rlwainwright: Yes, I would love the UMC-1 but it doesn't exist yet and my budget is already blown.
Meiwan: Thanks - I'll check out your suggestions.
Thanks - rev
