If you want bare bones get the 975. The PEQ and REW are a tweakers dream and when used as room correction it will always be available for re-tweaking if you change something. But in reality, how many of re-do our systems such that we have to re-do room correction so frequently. I think you passed the value point of no return awhile back especially if you don't have a dedicated room to really tweak.
