Onkyo TX-NR5009

Onkyo TX-NR5009 and TX-NR3009 are two high-end integrated 9.2-channel AV receivers.

I did a quick research online about this multi-channel Onyko receiver which will replace current Onkyo TX-NR5008 model. Here is what I found.

Onkyo Receiver Connectivity

The Onkyo TXNR5009 seems to be very versatile AV receiver if you look at numerous connectivity options. Connect up to 8 HDMI devices to TX-NR5009 HDMI inputs (it even has 2 gold plated inputs), 2 USB devices and get video inputs from your PC thru RGB input.

There are few inputs that are specific to this brand. One is the Universal Port for adding Onkyo peripherals. Second option is free app for your Android or iPod touch or iPhone that turns your smartphone into a remote control for Onkyo receiver.

Of course network connectivity is present as well. It is kind of standard nowadays. You can plug in wired Ethernet out of t he box, or get optional UWF-1 wireless LAN adapter. I would say wired technology is still more reliable and provides better quality.

When the TX-NR5009 is connected to the internet, you can listen to Internet radio stations and streaming music services, for example Spotify, last.FM, Napster AUPEO! or vTuner. It is not clear if Pandora services also will be available with this receiver.

You can also stream content locally from your computer using DLNA 1.5 features or connect USB storage devices directly to your receiver. USB thumb drives also are supported.

This unit is compatible with wide variety of audio formats starting from audiophiles Super Audio CD down to FLAC, WMA Lossless, WAV, AAC, Ogg, and MP3.

Keep in mind that it is 9.2 channel device! That means you can use benefits of Zone 2/3 capability and play stereo audio from different sources in two other rooms.

Engineers have implemented something called Audyssey’s MultEQ XT32 room-correction and equalization technology which is designed to provide best possible audio performance in very room regardless of its shape and acoustics.
