I have checked out logitech z-5500 5.1 setup and they are amazin sounding spks,deep bass, and punch, also checked out several 5.1's from creative g500,550,I-trigue5600, t6100 but I did like the G500... I have a x-fatility with 5.1and 7.1 but will be going along with the 5.1, Opinions as to which will go best... Price between them not much of a difference, no issue there..
