I'm one of the original Bricasti M1 owners and one of their main guinea pigs.
Enjoy your new M1. Its an amazing DAC. It will break in fairly quickly. Just send signal through it for a week and you should be good. The key to maximizing the sound quality of the M1 is to experiment with the filter sets. The linear and minimum phase filters present very different characteristics. I lived with the original linear phase for some time and couldn't imagine the M1 sounding any better. The introduction of the minimum phase filters was a complete game changer. Now I could never go back to the linear phase filters. Others might hear things differently. Play with them and dial in the M1 to suit your taste.
