Sbrown is going to be using the outlaw monoblocks.
Axiom is coming out with an amp specifically for the LFR's as well...
I would get the XPA-5 out of the list you have presented. if you get 5 UPA-1's you will have 1,500VA worth of power supplies, if you go with a XPA-5 you will have 1,200VA worth of power supply, for less than 1/2 the price. Personally, when i am buying an amp the power supply is one of the largest factors that goes into my purchase, next is the power rating when the impedance halves.
Outlaw does not list their power supply ratings, at least not what i could find anyhow..
