A little late but have had enough time to sit down and 'review'.
Really cannot complain at all. Albeit my only personal comparison is the TV's built in speakers and some very short use of an old Creative Inspire 4.1 speakers. Really does give it that big theater sound which is nice. Not too overpowering in any aspect if set right but can be pushed and still handles itself. Case in point playing Split Second on the PS3 which really exercises the sub to say the least. Also surprised at music quality on this thing. Usually you see reviews where surround systems are good at movies but not music or vice-a-versa. This seems to be real flexible in that respect.
So far test material has consisted of such:
Mission Impossible: Ghost Protocol DVD (Standard DD5.1 soundtrack, bitstreamed from PS3)
Numerous movies aired on TV with 5.1 audio. A couple on FX and a lot on the premium channels
Split Second game via PS3 (5.1 PCM)
Cool features I have noticed that have made this a nice buy:
1) HDMI-CEC control. Although the connected TV does not support it (The 42" Panasonic in the family room has it but is not being used with the receiver), the PS3 does. With a quick 2 second reprogram of the remote, it allows control of the XMB and media playback functions via the receiver remote over HDMI with no extra hardware like an IR dongle. VERY handy. Even handles powering on and off via remote without needing to touch a controller.
2) Universal Port with an optional HD Radio module and possibly even wireless speakers if I am reading the manual right. The former is one of those things that would be far from a regular use but if prices come down I would not make a second thought on purchasing it. I already own an in-car HD receiver and a portable one and am fairly impressed by the technology with the stations in the area and think it would be a nice compliment to this receiver.
Overall I am very happy with the purchase and don't really have any cons to speak of. Other than the included speakers (I should note, having the ability to swap them out is a big plus for down the road) being a tad big especially on the front channels and lacking a little bit of high end in the out of the box configuration (I believe I have the treble setting at +2 or +4 db, everything else is at 0), not anything I can really complain about.--
I swear, some people should have pace-makers installed to free up the resources. Breathing and heart beat taxes their whole system, all of their brain cells wasted on life support.-two bit brains, and the second bit is wasted on parity! ~head_spaz
