This is not to sound derogatory, because of restrictions and so because cheap. Cheap it is not. Is nevertheless an Onkyo product. Wanted me only Onkyo down, because they were the boxes already present, am then encountered TEAC and I've decided for. At Onkyo, I had too much reading about Softwareprob's. I was not disappointed. The AG-500 corresponds in principle to a 515-he Onkyo. Has slightly less power (5x130W instead only 5x125W), but that does not matter. Because of the neighbors, I've been thinking, if I do not yet headphones DETERMINED me. But may also be due to the chosen music, are not hit. Regardless, the device is simply good. HDMI to the hilt (IN and OUT), loud as hell ;-) and the sound is awesome. One hears a sudden things in songs that not glaubste. So for the average guy who wants a really good radio, highly recommended. Oh yeah, he also has Internet radio. Was also important to me. , Sounding good, but you can listen to Spotify only with the premium account, which I would not. Therefore use the other options. One has with the device. DLNA works great. The app for control I have not yet tried it yet, I can say nothing. The only thing I miss from Yamaha, is the second outlet in the device. Had since the sub off. I now had to seek a radio outlet. Goes well, but you could make improvements. For the AG-500 has a USB port at the touch of Lan's. That's really good thought. A small switch on it and radio, game console and TV are online. So, I'm not disappointed because it was cheap. You have to get only :-(
