Hi Foolish Pleasure,
Since this is an industry ad, this may not be the best place for a critique of this new product, much like it is not considered good form to criticize a product or price in a for sale thread. There are other areas of AC where such a discussion is more appropriate. And if one doesn't exist for the M1, it might be a better idea to start one.
That said, welcome to Audio Circle. This is a great site for discussion of all things audio. But reserving certain types of discussions for certain areas of the site helps keep things civil.
