My room is 12x14 with 8 to 14 foot vaulted ceilings. This is open to a 8x10 dining room (8ft ceilings) to the left of where my left speaker is. As far as what system synergies Ive had before, my most memorable was the requests hooked to a yamaha amp!!! (granted the amp did shut down every once in a while). My 802's with the Yba Integre dt gave wonderful sounds as well. On the other end of the spectrum, my dynastats sounded bad no matter where i placed them or what i hooked to them, especially the rogues. My last setup before the Nad was my 1.6's with the 383 levison. This setup had tremendous dynamics but a very sterile sound that could at times rip your head off. My rogue monoblocks just didn't have the oomph to drive my maggies or 802's to satisfying levels but i loved the smoothness of the midrange. To those who have answered this thread, thank you so much for your input!!
