One thing I will add about Room Perfect. It is the easiest room correction software I have ever used. I have used both Audyssey and DIrac.
Your first measurement must be in the MLP. All other measurements should be random around the room at different heights and locations. The intent is to get to at least 90% Room Knowledge. After each measurement, the cumulate Room Knowledge is displayed. Once you achieve 90%, you are asked if you want to perform additional measurements. It typically takes 4-5 measurements in my room to get to 90% but that will vary with the room and the locations you use. I have been taking additional measurements to achieve 95-98% Room Knowledge.
