I would expect that the REW software combined with the Parametric EQ would be able to customize the sound in any room to the users preferences as well or maybe better than XT32 but...it will take some effort to learn how to use REW to set up your room with the PEW in the 975. Also I would expect that from what Outlaw has stated about the 976 using similar topography to the flagship product they are working on, that the 976 will have even better sound than the 975.
