Summary: It's OK, but won't blow you away. This is just about as cheap as any 5.1 home theater system can be sold for without being complete garbage. I did have this for about a year and a half and enjoyed it while I had it, but since upgrading the difference is night and day. The receiver is halfway decent, and the HDMI passthrough is by far the best part of this entire system. If you use it to play loud music on a regular basis, the speakers will die on you in a few months.
Summary: I have owned this unit for a few months now. If I had it to do over again, I'd spend a few bucks more and get the Yamaha with the networking. This Onkyo seems to have an HDMI handshake issue with my Comcast X1 platform digital box. I know others have complained about Onkyo dropping audio too. The audio will intermittently drop for 1-3 seconds. I have even seen a dropped picture for a few seconds.
Summary: Pros: Decent sound for price Independently adjust levels for each speaker/sub easy set up/color coded wires lots of inputs nice looking Cons: Different inputs or devices have different volume levels i.e for cbl input where I have my cable box going, around 50(about half way up) is a good slightly loud level however for the game input where I have my xbox hooked in about 25 sounds the same.
Summary: I bought the HT-3400 last year and it is virtually identical to this one. I had an initial failure within 3 days and had to get it replaced and so far this one is working, however Onkyo's quality is nowhere what it used to be. I liked the set up in the beginning because it was such an improvement over the tiny speakers that came with my TV, however over time I came to realize that much was lacking.
Summary: My 4 year old son thinks the "Oink-O" system is very pretty. This was purchased to solve the dilemma of too much HDMI and not enough inputs on the television. Also I had wanted a 5.1 or 7.1 system for a while but had neither the space, money or patience to build a heavy duty system piece by piece.. The image quality of the BR and the Samsung HDTV we have is great. The sound? not so much. Solved that problem in less than 30 minutes.
