At 600 watts RMS for the 4-ch version the price is definitely right.... I was looking to spend about the same on a 50x4 so to get 175x4 it's probably worth looking into and even if the power output is exaggerated by 50% it's still going to be plenty of power for the 6.5 speakers I'm pushing, even when I add 4 more and drive it at 2ohm.
