I bought the TX-NR509, since this receiver was the chip test in the upper box and Internet radio provides. Unfortunately, and I have to confirm when the web radio with the dropouts: Again and again misfires and then you have to re-call the sender. And despite local Gbit LAN and functioning DSL6000. Parallel I still have a "normal" Web Radio and works fine on my network. Even after the firmware update (version of 8:08:11) there were sporadic disturbances. Although now starts the 509er the stream again by itself, but who would buy a car in which sporadic stops the engine? If Onkyo still get this problem at hand, then one could speak of a really good AV receiver.
