Sure, there's a defeat switch on the MQ112, so very easy to bypass the internal circuitry. I hear absolutely no degradation whether switched in or out with all eq settings at default 0 values. That is the main reason I went with the MQ112, putting my trust in McIntosh to not alter or degrade the sound.
To correct for room deficiencies, I use the Anthem AVM 90 included, ARC® Genesis. I also like to use Dirac Live on two of my other systems
My system - Power: McIntosh MC312, Pre: Anthem AVM 90, Main Spk.: MoFi Sourcepoint 888, My room is also difficult, in a basement, about 1300 sq ft
