That's a pretty beefy amp with nearly 200W @ 8 Ohms and 300W @ 4 Ohms IIRC. That said, I would expect that we will continue to see more amplifiers delivering 250+W @ 8 Ohms over the next year or two. It does appear to be a rather good value. Personally I'm usually a fan of shared power supplies for multi-channel amplifiers leaving more on tap for each channel in real world conditions while saving some costs, but both can be executed well.
As usual the Emotiva gear is priced very competitively. Tough call. While slightly more expensive (not much), I have a little higher confidence and preference for the Outlaw amps such as the 7200, 7700, and of course the upcoming behemoth 7900 (at ~2x the $). While amp specs don't tell you everything, I do very much like the 119-120dB S/N spec of the Outlaws ove the 100dB spec of the MPS-2. If it were me, I'd probably spend the extra $300 to get the balanced version of the Outlaw amp, but both look like good values, and I'd still consider waiting things out. My 2c...
