Well no actual experience with either but as the Helix is designed to go inside its processor you won't need additional power-ground-turn on-interconnects etc. Whereas the Mosconi is stand alone to any amp needing all of the above. Just for packaging sake I'd go with the Helix unit. Especially since you already have the processor. But the Mosconi is capable to be used with anything in the future if you choose to change down the line.
