Yes, I have the board and yes you are correct.
I checked with Bricasti.
The upgrade is firmware!
Easy to do. Brian thought it would add two more filters and that is about all.
They are such a pleasure to deal with
Bricasti MDX upgrade
I have a Bricasti M3 DAC with the 1.08 MDX board. I see they have come up with an upgraded MDX board ( now 1.09 ). I believe its a hardware upgrade at a significant cost rather than a downloadable firmware upgrade.
Has anyone upgraded their DAC?
Is there an audible difference? If so, in what way?
And last, is it worth the cost?
