The Plinius is a superior amp, I don't care what the other power ratings are and they won't matter since the speakers are 88db efficient @ 8ohm. Choose a good head unit with a sub-out, you may find yourself longing for the bottom octave sometime down the road and it would be easy to match a good sub in the system (there are plenty out there). The Marsh is made in Thialand..YIKES !!!
