Beautiful system lineup. Just looking at the room layout, I can almost hear it. I bet it has optimum clarity even maybe too much. Reasoning is, other than the rugs, everything else is mainly reflecting and a lot of diffusing with almost no absorbing. My thought is that you will eventually want to tone down the room as it may become too fatiguing listening to it as is. Either way, with your equipment, I can only imagine how great it can really sound. Enjoy the room acoustic journey.
