    @ajc9988 Couldn’t have said it better myself.


    The reference boards look of high quality and the fact that they are filterless is definitely a plus. I’d say it might be a lot easier (and possibly even cheaper too) to have separate power supplies. As for supporting peak current draw (mostly needed in the bass region since a lot more energy is needed to move the cone), for this I would recommend replacing the onboard capacitors, but that can be difficult since they are of a surface mounted type, so it’s difficult not to ruin the traces or pads on removal without a hot plate.
