Glad I ran across this thread. Two-channel amps with integrated power supply would be great as "amp packs" on 2-way actives. Earlier in the thread, you said that power can go much higher but eventually at sonic expense. Do you have a rough idea on where that power level lies with a supply made specifically for the Maraschino?
Mono units with integrated power supply would be great sub amps too. Maybe goose the power a bit for this application?
I'm looking at this for an upcoming 8-channel "stereo" system. 4-channels for active 2-way main speakers, and 4 channels for sub "swarm." Every speaker/sub built with amps attached. Volume/crossovers/EQ will be handled digitally. All 8 amps fed via balanced XLR. Maraschino could do well here.
So I bring up power from my perspective, as food for thought. All the various speakers I may bring into this system can take copious amounts. Geddes Abbey is definite, and possibly others. Danley SM60F, Ohm Walsh, and Pioneer EX all appeal to me for various reasons. I consider 200W/400W/ch into 8/4ohm a good target power level for the main speakers. This will be adequate with the Geddes and Danleys for home use, although both can handle more power. It's not clear how much power the Ohms can take but some veterans swear by their 500/1000W amps for best dynamics. So while a really clean 200W/400W amp wouldn't be theoretically enough to max out these speakers under all circumstances, it should be enough for 99% of real world use. Most of my listening isn't very loud but I don't like excuses when the volume does rise a bit.
Sub drivers can often take massive amounts of power too, some between 1000-2000 watts. 300/600W seems like a good start, and 500/1000W even better. I completely "get" that this is likely outside the Maraschino design spec, so I'm not banking on this as much. Still, class D makes tons of sense for sub amps, and while common wisdom is to use any old thing for the subs, I think they deserve a little love too. If you make too many compromises, they start adding up!
Anyways, appetizing stuff Tommy. Looking forward to reading more about them.
