What speakers are you using that will allow Tri amp. I know Sonos Faber lilium speakers do it, and they are tempting but my room is too small and the bass drivers would overwhelm the place.
Are u planning to remove the internal crossovers? I guess that would be pure triamp. Otherwise you'll be competing with what's going on inside the speaker but that may be OK. I really think you need to try biamping. I doubt many people in this universe are triamping, and if so you'll probably never find them to see them in person. I would like to personally visit a triamp Domain as the systems are extremely technical and well thought out if done well. A true connoisseur.
