Have you considered monoblocks for each channel as an option? If so, you might consider Outlaw as an option? Their 2200 is very well respected and having a dedicated amp for each channel is a good thing. The $674 price is also not shabby for what you get, 200 watts @ 8 ohms, 20 Hz - 20 kHz, <0.05% THD; 300 watts @ 4 ohms, 20 Hz - 20 kHz, <0.05%.
