I bought is system as my 2nd system for my house (different room). My other system is also an Onkyo TX-SR805 with high-end Energy speakers in a 7.1 setup.
I setup the HT-S9100THX and discovered an interesting issue. I am testing with THX Optimizer (as seen on movies like Star Wars and the Avia tuning CD). One of the things it does, it will put white noise into each speaker (one at a time) so you can make sure you wired up everything correctly (basically so that left is left, and right is right, center is center, etc).
The problem I have is when it goes to test the Surround R/L and the Surround Back R/L, it puts the sound in the front and center speakers (instead of the correct speakers). I tested to ensure they were all wired correctly using the Onkyo setup menu. I figured problem was with a sound setting issue, but I have tried every setting including Direct and it won't pass the THX Optimizer tests (makes white noise in the wrong speakers when it goes to test the surrounds).
I am using a PS3 for my BlueRay player just like my other theater setup. I can run these exact same tests on my other system and everything works as it should.
No doubt, when I set to Cinema-THX is sounds good in movies such as Star Wars (I was surprised how nice this system is for the money), but can immediately tell that the surround sound is not accurate to the movie (because it feels emulated, which I believe these tests prove to be true).
I have tried setting the PS3 from Bitstream to PCM and it doesn't make any difference. I have everything connected with HDMI.
