Summary: The receiver functions beautifully. The only missing feature would be the ability to rename different inputs (label them HDMI 1, 2, etc then give a different display name). Aside from this, the touted app is awful. I've tried every version for android and even after several updates it remains buggy. If you are purchasing this receiver specifically for the app support, you might want to find something else.
Summary: But Amazon's return service was outstanding! I couldn't find another used one in my price range so ended up 'upgrading' to a used VSX-1022 for a few dollars more and was very pleased with that. I'm sure this was a good product but since I don't know whether the product is fragile or I just had a bad experience, I can't give it very many stars.
Summary: This is a great system with lots of great features. Loved using the microphone placed in the viewing area that calibrated all speaker volumes. Unfortunately Pandora is not working even though it is working on other devices in my home and other internet radio stations are working on the receiver. Been calling pioneer for two days and keep getting a busy signal.
Summary: This unit might be great for a home theater system, but I bought it to provide music in our office because it could plug into our network. After a couple of weeks of tweaking it we now have it working adequately, but I only rated it a 3 for the following issues: 1. You have to have a TV connected to the unit if you want to use all the features. Pandora and internet radio only work with a TV screen (which we do not have).
Summary: Pros: Low cost, good quality Cons: Limited to only a single set of speakers, setup was a bit difficult. Met most of my needs. However, it would have been great if it had A & B speaker capabilities as I would like to use a set of remote wireless speakers on my patio without having to purchase a second receiver.
Summary: There are a lot of nice features and having all the HDMI ports is nice. It works great with one big exception (if you ask me)... Without the TV on, it is almost a brick. You basically have two choices for using this receiver. Turn your TV on and use the on screen menu system or use the smart phone app to control it. There are so many things you CANNOT do using the remote that having the remote at all is almost worthless.
