Ovator S400...... oh, NICE! I'm running the Yammie NS-777 (x2), NS-555 (x2), NS-333 (x2), NS-C444 (x1), and two Yammie YST-RSW300 subs, 1 wife, 2 dogs, 1 cat and a budgie!
Edit: I only use the NS-777's (bi-amped, not bi-wired) and the subs for music. The surrounds are only used for movies (using Openelec) on the Pi with HDMI sound output.
