I suspect that if people were not locked into DSP's, the 861 would be a value option on Audiogon. For that reason alone, I struggle to see how M cannot produce an 861 replacement. M even continues to perpetuate its connection to cinema, with alliances to Barco, etc. I know if I had a sizable investment into DSP speakers, with a passion for cinema, I would be fighting mad right now.

I have said it a couple times, why doesn't M just license a manufacturer, while using M DSP connectivity?
