Recruit: Oh ok - I thought you were talking about only one G55 and were thinking of adding another amp for the rears (not a G55).
I was thinking of doing the same for some time now, since the G55 seems too small to drive my 5x BW804 loud enough without getting way too hot and distorting the sound or shutting down, but I finally decided to go for the Classe Delta CA-5200 (5x200)
http://www.classeaudio.com/delta/specs/ca5200.htm (still waiting for it though) and either sell the G55 or use it in another room with smaller speakers. I tried a Rotel 2x200 beast with my L/R 804's and the difference in power was absolutely stunning. I bet the Classe will sound even better in a 5 channel configuration ..
