To start off, the VSX-1122-K is rated at 90wpc (measured from 20Hz to 20kHz with 2 channels driven at 8 0hms) and includes audio decoding and processing for most surround sound formats, including Dolby Pro Logic IIz and an additional wide surround processing format.
Also, this receiver features Audio Return Channel and an HDMI standby pass-through feature (which allows audio and video signals connected via HDMI to pass through the receiver even when the receiver is in standby mode) are included. For video support, the VSX-1122-K includes 3D pass through and 1080p video upscaling via HDMI connections (there are seven inputs and one output).
However, here is where it gets really interesting. The VSX-1122 can access iTunes via Apple AirPlay. Content stored on iPods, iPhones, and iPads can also be accessed via the USB input (connection cable provided). The VSX-1122 is also HTC Connect compatible. For more control and management of music files, this receiver can also take advantage of Pioneer's Air Jam Apps.
In addition, the VSX-1122 can also access both internet radio and content from DLNA compatible devices, such as PCs and media servces.
For added convenience, the VSX-1122 can be controlled from Apple and some Android devices via Pioneer's iControlAV2 Apps.

Is this a review or a press release?
This site is always composed of press releases thinly disguised as reviews.
Thank you for submitting your comments regarding my site.
I do a variety of short product overviews (such as Products of the Week), and both short and long reviews – I do in-depth reviews on a lot of products – which often times include additional product photos, and, where appropriate, video performance tests – here is a list of my most recent ones:

I usually publish three or four long form reviews per month, supplemented by additional short reviews, product overviews, as well as newsworthy product announcements (in which I also provide some additional context), including coverage of trade shows such as CES and CEDIA. In addition, I write numerous resource articles, such as buying and setup tips, as well as articles discussing technology features and innovations.
If you need to see more, feel free to dig in deeper into the site and subscribe to my weekly newsletter.
Before throwing out a phrase, such as “always composed of press releases thinly disguised as reviews” – you might want to take a closer look.

I stand corrected. My apologies to Mr. Silva.
Thanks for the quick review of the vsx-1122-k. I have been looking at it for awhile.
The model has been discontinued however. Except for a handful of retailers, it is no longer available.
In its place will be the 1123-k which is to be released at the end of March 2013.
My first look at the new 23 series Pioneer Receivers is at the following link: http://hometheater.about.com/b/2013/03/05/pioneer-announces-four-23-series-home-theater-receivers.htm
