other than power the x5200 has al24 vs x7200 al32 bit processing and a few other bells and whistles, the onkyo and itegra has dropped the auddessey room correction and have thier own in house correction that does nothing on the LCR, huge mistake in my view... the clear winner are the denons right now ... best thing is to wait a year or so... meanwhile will be getting the room ht atmos ready... have 4x m3 in-cieling on order
