So, to better answer the OPs question, I much prefer having the system to the side, and not between the speakers. In my youth, I had a rather grand system (Accuphase, bi-amped into big Infinity speakers) and it was to the side. I was able to "see" the soundstage between the speakers, looking into the front wall with wood diffusers. In my present house that layout cannot be achieved. Thus, building a dedicated sound room I can achieve what I believe to be best, and that is for having the system to the side of me and the speakers with the amp between them. The front wall will have high quality diffusers in the middle. A much nicer view of nicely done wood diffusers as opposed to a rack of electronics, in my opinion.
