Fuzz I have tried a bunch of surrounds, and I could never tell the difference, as j says maybe with 5 ch music they would, but I can not stand 5 ch music, lol, I wan't music rite in front of me, close my eyes and have my front left and right disappear as they are blended into one perfect orb of music coming straight down the center of the two... But anyway with movies I find that no matter how much you spend on surrounds you won't notice the difference, and that budget would be better spent anywhere else in the system.. I use 200se's and have had so many speakers mounted up there Mirage omni poles, jamo di poles, psb bipoles, and a bunch of other bi, di omni poles as well as normal bookshelfs... I just can not hear the difference, even with heavy surround movies, the surrounds light so sporadically and for such short periods of time with such immaterial sounds... Its normally a car door, footsteps, wind, rain, ect, never anything that lasts long enough to really analyze it or notice the quality of the sound....
My brother argues with me about this, could be because he spent $900 on a pair of surrounds for his HT, but to prove my point we threw my pair of elcheapo dayton bookshelfs on his stands and he half way admitted that he couldn't tell the difference... Granted his opus surrounds look really impressive, they do the same thing a $25 pair of bookshelfs do... Its an effect speaker, hardly ever voice, music, or anything detailed, that money would be much better spent up front...
