Roon Active Crossover (or How Good is RAAT synchronisation)?

Fascinating topic. I found this after doing this myself and thought to myself “I wonder if anyone else has tried this”? I’m prototyping a speaker design (for my own consumption) and my analog active crossover hasn’t shown up yet (keeping this one analog - Marchand) so in the interim, I thought to throw together two Roon endpoints as a group and use DSP to create two crossover points, a simple LP and HP 36dB/oct. So far so good, it’s working and keeping music in sync to the best of my awareness…
