If you really want to do your L-shaped room some justice, the UMC-200 has a very powerful manual feature in P-EQ. It just so happens that HomeTheaterShack has REW, so if you didn't already know, their is a section of this forum that can get you started and with the microphone of your choice you can do wonders. To me REW and a P-EQ will take you past the "set it and forget it" room correction softwares.I went to the Emotiva summer show in Boston June 22 and got a UMC-200 & UPA-700. It was to replace a Denon AVR-2309. The Denon worked but did not like the Magnepan MMG W speakers 5 ohm impedance. It got quite hot. The Emotiva gear sounds better with more detail. What I like most about the UMC-200 is the speaker trims on the remote. On the Denon you had to stop the movie and go deep into the menus to adjust the speakers. With the Emotiva just hit the buttons on the remote to trim the surrounds, sub or center speakers. This is important as cable is different on every channel. The only thing that did not work was EMO-Q. This is due to the Magnepan's and the L shaped room. The picture on my Samsung has better blacks and maybe a bit sharper with the UMC-200. The UPA-700 is just warm to the touch and more dynamic than the Denon. Emotiva has a 30 day trial so you can try it in your system.
