This is fun! I put my (slightly oddly setup) system into it but I couldn't reconfigure which set of speakers were connected to which amp, or reorder the signal chain at all. Is this a planned feature? E.g. I have an integrated all-in-one amp that drives my main speakers but I tap off the pre-amp output into a secondary integrated amp that drives two secondary sets of speakers but your app assumed that my second amp was driving all six speakers and so spat out a warning about power levels...
