The ICE amp module is also a switching amp and will share those high efficiencies for converting wall current to power at the speaker. But when we originally looked into the possibility of using the ICE amp modules they came with their own switching power supply as part of each module. We found this limiting to one of our main design parameters of having a massive analog power supply available to all of the channels. Beyond this show stopper, there were also the limitations of the module itself. Though it would be easy to implement for sure, we really wanted more control over every aspect of the amp design, which designing from the ground up gave us.
