For me, personally, I can't see buying an outboard room correction device that costs almost twice the current price of the 975. However, full disclosure, I have exactly zero experience with room correction of any sort beyond my trusty SPL meter and using the on board adjustments of my processors. I suppose I might give auto-correction/setup a try if I ever purchase a processor that happens to include it, but I can't see it being a selling point for me and I definitely am not the target demographic for the DDRC-88A.
