Onkyo TX-NR515

If you thought midrange AV receivers were going to max out at six HDMI inputs, you were wrong.

Onkyo announced its 2012 line of midrange AV receivers this morning, with the TX-NR515 and TX-NR616 each featuring eight HDMI inputs, enough to handle your cable box, PS3, Xbox 360, Roku LT, Apple TV, and three other home theater gadgets. The front-panel HDMI input on those two models is also MHL-compatible, which means you can connect a compatible smartphone or other MHL gadgets like the upcoming Roku Streaming Stick.

Here's a quick breakdown of the new models and most important features:

Onkyo receivers are always jam-packed with features, but the new line seems even more robust than most. The TX-NR414 is likely to be an incredible value (Onkyo receivers generally have a street price much lower than list) with enough features for the average person. The two step-up models are also attractive, although none of the step-up features seem particularly worth paying for. (The MHL port is cool, but the front-panel location would make it awkward to have a device permanently connected, like the Roku's Streaming Stick.)

The one surprise is that Onkyo is choosing again not to feature built-in AirPlay compatibility, which was featured on competing Denon and Pioneer receivers last year. It's not exactly a deal breaker for Apple fans, who can choose to add an Apple TV or Onkyo's upcoming UBT-1 USB Bluetooth adapter for wireless music streaming, but I've found built-in AirPlay streaming to be a pretty compelling feature in an AV receiver, especially compared with other media-streaming features.
