lot of phase cancelation happening here, it it M/S but not decoded? something's off. looking into the R88A right now as well, but cant figure out on the spot whats wrong here. Is the face of the Center inverted or something? keep it up!
@@jeandado It's possibly just comb filtering...I hear what you hear, but it's the nature of the room. I use the R88A regularly and have noticed it thrives in absolutely dead environments and large rooms with diffuse reflections.
