Summary: OK, so this is really nice receiver with great sound. The button labels are a bit difficult to see and could be more well lit - especially in a theater type room and the speaker cables could be a bit longer, BUT the reason I give 5 stars is because of they stand behind their product. My unit had problems when the warranty was questionable and I was trying to see if it was covered before I shipped it in.
Summary: Nice product for price. Cannot ask more than this. Was looking for a descent home theater. Read the reviews of this product. Perfectly matched my requirements. So thought to give a try. Wasn't disappointed at all. Instead, got surprised by the quality of the sound this machine can produce. The installation is pretty straight forward. However, getting along with the AV receiver and all those settings can get little tough.
Like fine wine this HTIB system opens up more every day.

Summary: So I have had the system for two years now. I have got to say that I am still very impressed with the performance and it seems to get better every day. Though when I first bought the system I was not very impressed. It didn't have a natural sound. The sounds seemed very digital and tight but, as the drivers broke in the sound started softening and becoming quite full. The drivers took quite a while to break in.
Summary: I have owned the Onkyo S9400THX setup now for almost two years and can safely say it was an excellent purchase. The sound quality is excellent and the setup was relatively painless. The side and rear speakers sound good but the build quality is what you would expect from a 7.1 THX certified system for under a grand. I was very impressed by the quality of the front and center speakers, they sound great and feel sturdy.
Summary: ITS BEAST a BEAST of sound while playing videogames and movies. THX enters at volume level 82.. i almost never get that loud while playing it would be suicide i m around 65 70 at that pretty loud. Currently have it with my xbox one and i play a lot of BATTLEFIELD 4 . its simply amazing.
Summary: When getting ready to purchase a 7.1 surround system read more than a few disparaging reviews about this system. But went with what it offered in so much as THX certified sound, along with the speaker package included and power. I can happily report the system sounds better than advertised, setup using the provided sound analyzer and microphone was a breeze.
