Are we talking about M60 actives? I have those across the front with a Marantz processor and the analogue version of the DSP33. I don’t know M6s.

I sat them down, ran room correction in 2016 and forgot them. It is a pleasure to listen to in our mail living dining area and the Roomba plays along some morning during my coffee. They can fill the open room with a full, clear, meaty sound.
