I have heard the M1’s at shows and am always floored by them. Of course there are at times that I wish they went lower. I don’t think the goal of them is to sell as many as they can. I think it’s about them achieving a certain level of performance that only the select few can afford. I could see some top studio professionals or mastering studios pick one up, and a few go to the distributor’s highest profile clients who can afford them with the bat of an eye. If they sell a dozen of them in a year worldwide, they’ll probably consider that a success.
Oftentimes speaker manufacturers will create models that are extreme like this. Consider the MBL Extreme for over $330K. And yes, I do know people who have bought those. So there’s a market for them, albeit not accessible to most.
