I’d go with Electrocompaniet.Not if they're bridged as I suspect, not with those speakers.
My friend has the Alexia’s they are a pig of a load for and amp, they go down to 0.9ohm in the bass. They need amps with current to get the best from the bass, big current that can "almost double" their 8ohm wattage into 4ohm and again into 2ohms. And being 91db they need >100w @ 8ohms or more.
Both amps are brutes and should work fine
PS: from what I see now my money’s on the Bat, the Nemo monoblocks "seem" to be bridged stereo amps, not to good for current and stability into a 0.9ohm load in the bass of the Alexia’s.
