Summary: We enjoyed it while it lasted, but it began having trouble with DVDs flickering and flashing and cutting out, as well as cable tv. We tried different cables and hooked them up to different ports. Nothing worked except switching to a different receiver.
Summary: I bought this as a replacement for a Harman Kardon which only had pass through HDMI (no audio capabilities). I have a lot of input equipment in my current setup: PlayStation 3, Xbox 360, Wii, Wii U, Ouya, PlayStation Portable, 2nd generation Mac Mini, and a Windows 7 laptop. The Wii, and the PSP are connected via component, and everything else is via HDMI with the audio from the Mac over optical.
Summary: I have found it impossible to adjust the sound to the various channels. The system has connected with my Comcast system and TV and now I cannot adjust the center channel using the receiver tuner. This has caused me to turn on closed captions to understand what people are saying when there is background music. I found this very frustrating watching the ice skating during the Olympics.
Summary: I liked this receiver when I first set it up. The sound was good and the setup was fairly easy. But the receiver only lasted five months before a major problem developed. The video has become very erratic in the past few days. the picture on my TV has started to flicker on and off very badly. I thought that it may be an HDMI cable, but the picture is fine when the receiver is on standby and I have the HDMI passthrough switched to "on".
Summary: I USED to love the Onkyo product line, was a big fan and spokesperson for the product. My HT-RC180 died exactly 2 years from purchase with a bad HDMI board. I am not the only one that had this problem. If you did a "Onkyo dead HDMI" you'll know what I am talking about. Onkyo agreed to fix it (they had a 45 day grace period after the warranty expired) and took about 2 months to get it repaired; there was a shortage of HDMI boards - that should give you an indication of...
Summary: Every 2-3 weeks the sound stops working and I have to do a factory reset to get the sound to work. Then I have to go through and reset everything back up. Like my internet connection and the speaker adjustments. I have talked to Onkyo techs a couple times. First time the tech was like it shouldn't happen and if it does again to call back. Second time support offered to have me drop it off at a service center. The closest service center is 4-5 hours away.
Summary: From Onkyo's numbering system, you would think the 525 would be the replacement for last year's 515. Wrong! It is the replacement for the 414. I had read good early reviews of the 525. However, I spent 2 days on and off with Onkyo tech support trying to get the 525 to work with my new Samsung 55" LED Smart TV. My 525 wouldn't play TV sound thru HDMI ARC or connect to my Wii game console.
