Pioneer Elite Reciever VSX-82TXS I really love the auto-soundstage for surround sound. Particularly gaming. It was lifelike before, but with the distances of the surrounds precisely leveled and the sub phase matched it is a truely immersive experience. I can tell pioneer put a lot more into their programming because all my Samsung did when "auto" adjusting was detect the level/size and adjust DB's accordingly. Barely any difference. On the other hand the pioneer took 10 min of various forms of pink (and possibly some other colors) noise in ea channel and used the info to really get the imaging right. I'm usually one to fiddle w the levels but I won't touch these settings.
