In my humble opinion, the Flex digital is too much money for the little your goodselves want to do with it. I think the Wiim streamers offer PEQ correction, if you can measure your system with a Umik microphone via REW. The dips cannot be filled by any system, so only the peaks need to be chopped. Which can be acheived by many digital streamers like Wiim. A Minidsp Flex digital might be overkill, without knowing what issues we have at hand. Besides, if you go for the Flex model with in-built dacs, then atleast you can use it to time align and seamlessly blend the subwoofer for 2 channel music, which might be worth the asking price. Just my 2 cents...
