Leo likes them a lot, and got an Onkyo TX-NR616 for himself. It's fairly inexpensive at around $386, with 7 HMDI ports in, and 2 out. So Leo could drive both his projector screen and his big screen TV. Drives speakers very well and the sound quality is excellent.
There are some things he doesn't like though. They promote the fact that it supports Pandora and Spotify, but it's very slow to get to it. It doesn't have a very fast processor in it. In most cases that doesn't matter because people most likely use something else for those features. They also do have an app to control it.
