Sure its an upgrade amplification wise. Presumably you are getting 3 monos for the L/C/R and using the RX-V220 for surrounds. That will give you much more dynamic headroom with its attendant benefits. To optimize it further you might want to run balanced cables to the monos which would be behind each speaker and then short speaker wire from the monos to the speaker.
The best upgrade would be ditching the RX-V220 and the Outlaw monos and buying the A1400-8 if you really want to "electrify" your system.
