Summary: I bought this system about a year ago. It still works great with no problems. The sound clarity is awesome. The features are great, you can individually adjust the frequency of each speaker. It goes very loud with minimal distortion. The sub woofer sounds good but it could be better.
Summary: I had this system for about 6 months and it sounds great! The 5.1 sound fills the room and the bass pounds. Especially when hooked to a Blue Ray/PS3. The only disappoint I had or didn't realize; when using the HDMI IN 1/2 into the receiver was only being used as a pass-through to the HDMI out. Meaning if you wanted the digital audio from HDMI input to play in the home theater, you also need to hook up the digital audio cable as well (optical or coaxial).
Summary: I purchased my Onkyo HT-SP904 directly through Onkyo a few weeks before christmas . It was a refueb Unit that came with the same warranty as the new item but much much lower. I paid $349 total shipped to my door. The system installed easily and sounds awesome . I would recommend the system to anyone considering it !
Summary: I am probably violating Amazon policy here because I actually bought mine on sale at Circuit City a couple of weeks ago. Sorry Amazon. So far I am very happy with the receiver, the dvd player, and the speaker system. It is a very classy looking system and it all connects up well together. I am running it on a Charter cable box (Motorola) and a Samsung 46" LCD tv (which I did buy from Amazon).
Summary: I purchased the HT-SP904 as part of a recent home theater upgrade. Overall the sound is excellent and the upscaling DVD player is a nice addition, but I really wish the HDMI was not limited to passthrough. Basically, any HDMI device plugged in to the receiver will need an alternate audio connection for full surround output. This is very strange considering the HDMI out passes the sound to the TV without issue.
