The Elipsa SE should have a deep wide lush soundstage. The room correction is screwing up the sound. I can't even imagine the Elipsa SE sounding in your face. This is the exact opposite of their nature.
Personally neither of these would be my choice for the these speakers. But I am not a big fan of integrateds. The PrimaLuma is nice sounding but you wil get better sound, especially crisper better defined bass with more power.
I drive my Elipsa SE with an Audio Research Ref 110 with KT 120 tubes. And I wouldn't mind more power. I have thought about moving to a Pass amp. The Elipsa SE are gorgeous sounding speakers. But they really benefit from top flight electronics.
