How good are Memphis amps?

I don't know much about Memphis and I IMO their amps look really nice. But how are these amps performance. I'm looking at some of their mono block sub amp, the Memphis 16-2000D to be specific.

not really sure the amp your looking at but they make some pretty high end stuff. I heard there old stuff was better than teh newer stuff, like most other amp manufactures, but its still better than anything you can find at best-buy
