2 out of 5 eggsHalf Baked

Pros: A lot of features and a lower price. It has not failed on my like other posters have experienced and I've had it for about 7 months now. It does sound OK. There is something to be desired from the sound but I think it could be fixed with manual adjustments.

Cons: Too many things do not work as advertised.

1. On screen menu only works with HDMI and can be hard to get it to even output HDMI. Gives some off the wall message "Can't Select"

2. The app is not robust. You cannot control zone 2 with the remote app for the phone. The one thing you need to control over the network you can't control. Go figure. The app does not connect reliably requiring the app to be force quit and restarted to realized that the WiFi is not connected. It also does not allow changing speakers in play or many other features

3. When playing for longer durations will shut off randomly after like an hour. May have been a problem with just my unit or some quirk with the sleep function. Does not happen often but really annoying in a movie.

4. You cannot output digital sources to zone 2. No Pandora, net radio etc. The only way to do this is to play the same source on both zones but in order to do that you have to physically rewire the speakers to separate connectors!

5. No 5.1 channel inputs. I know these are on the way out however Sony in their latest ploy to frustrate customers only allow SACD output over analog as if there were enough people interested in SACD to want to pirate it. Now those foolish enough to have patronized the technology are rewarded with frustration for the sake of greed.

6. The firmware download is only available in USB format which is the pain. The web access is much easier however the file download is in the wrong format on the website so the web interface will not accept it forcing you to use the USB which requires HDMI output. The web portal seems an afterthought as well. So much functionality could be included here that it really is a shame.

Losing count of the numbers here but the front panel is really hard to see in low light. Horrible layout of the buttons. You need bright lights to see the tiny print and the buttons are all in a row so you often press the wrong button. Remote is also not layed out well for finding the right button in the dark.

The manual is also badly written and has wrong information in several sections. Mine actually said it will not output the menus via HDMI when the reverse is true. This was updated later in the web version.

Overall there were too many things which did not work like all the advertising claimed. It's worth the extra money to get a receiver that lives up to the claims of the advertising or at least does not claim what it does not deliver well. I plan to steer clear in the future.

Other Thoughts: Under $300 I say it might be worth it if your expectations are not too high. $530? Forget about it. Spend your hard earned dollars elsewhere.

5 out of 5 eggsOverall good set-up

Pros: the auto set up is simple to use and there are a lot of options that this reciever gives you which is good enough for the aspiring techie/new audiophile/ home theatre. I have it set up with front hieght which quite honestly is awesome compared to surround rear IMO. It definitely added to my movies and games.

Cons: This thing is not friendly to the noobs of the audio world. I made this mistake and learned through the time I have had this thing that you need to have some knowledge. The only other con I would honestly give this is that does not have an option for a front wide set up.

Other Thoughts: As far as the reciever goes if you can get it for bellow $400 it is well worth it. I don't think that this item deserved some of the low reviews because of some the design choices (legacy upscaling, none user friendly interface etc.) because well TBH a bit of research should be done before buying a mid tier AVR. Besides all that though this thing is great and I love it because it forces you to learn rather than just duck walk you through everything.

1 out of 5 eggsGood while it worked

Pros: Easy setup

Cons: had it for about 5 months, and now the included remote trips out. wont change the volume, wont change the set presets for auto/direct surround options etc. none of the buttons on the actual unit work, except for the volume control knob.
The tech support/customer service is a joke. no one answers after you hold for 1+ hour.

Other Thoughts: had high hopes from pioneer, but wont buy a single product from them again.

4 out of 5 eggsGood receiver for price/category

Pros: 6 HDMI's
HDMI pass through for video and audio
Programmable IR remote
Excellent digital audio decoding
Phone app interface and music streaming

Cons: No back lit for remote
No decoder for analog to digital (the vsx-1123-k supports this and is an additional $100)

Other Thoughts: I've used this receiver for 2.5 months at the time of writing this review, and I'm very satisfied with this purchase.

You do require some tech knowledge for proper configuration of your home theater environment.

I purchased this device strictly as an HDMI receiver for my Home Theater PC. At the time of purchase, the unit came with Pioneer's SP-FS51-LR tower speakers at no additional cost. I completed the 7.1 surround with NXG's NX-BAS-500 sub and Pioneer's SP-C22 with 4 x SP-BS22 speakers.

Primary audio sources for testing:
Bluray DTS-HD 7.1/5.1, DTS-EX, SACD

Other audio sources:
320k mp3 and FLAC over wifi

It's hard to describe this system without having it turn into an article. The system has fine tuning for the advanced audio enthusiast but still has a quick configuration setup that does a pretty good job for the novice.

The phone app does a good job controlling the receiver. It also allows quick and easy streaming of your favorite tunes from your phone over LAN.

The unit does support Zone 2, but you will have to choose between 7.1 or 5.1 audio with zone 2 .

The IR remote has limited program-ability to work with a wide range televisions.

The unit also has HDMI pass through which lets you watch tv from and HDMI source without having the receiver on.

Last firmware update now supports Spotify.

3 out of 5 eggsNot as impressive once you get it home.

Pros: Has a lot of features you can't find at this price point:
Sound great (infinity Entra II surround).
Cell phone remote app
Network streaming from Windows 8 works great
Firmware update was painless

Cons: NO 5.1 Analog inputs - only 1 Optical.
On Screen Display only outputs to HDMI - Component and RCA will not let you see the config menus etc.
Zone 2 will only output analog sources (no Pandora, Internet radio, HDMI input audio. You have to wire RCA just for zone 2 to play anything. If you want to switch between outputting same content as the main room (called Speaker B) and Zone 2 (separate source) you need to rewire the speakers to the unit. They have separate terminals rather than allowing you to control the function digitally.
OSD is really lame looking and there are very few options compared to previous units I've owned at this price point.
Front panel buttons are impossible to recognize in the dark and labels are tiny. You need a flashlight to find the right button.
Remote buttons are tiny and somewhat confusing. Forget trying to use it in the dark.
NO PC CONTROL AP. The unit does not have a webserver for controlling it from you PC or it does not work in Windows. The manual mentions being able to log into the Receiver from Safari but I was not able to get it to work.
The Manual stinks. Real confusing and the links are such on the CD that you get routed between the local version and the online version easily confusing matters more.
The Phone control app for Iphone 4 cannot control zone 2 (WTH right?) forcing you to go to the receiver to change content, volume etc. further discounting any remaining value in the zone 2 feature.

Other Thoughts: They rushed this thing to market and cut a lot of corners.

1 out of 5 eggswhere did the quality go

Pros: Looked good. Had all the hyped goodies.
Had high hopes for something that marketing convinced was a quality product

Cons: sheetmetal thin and flimsy to the point you think you bent the sides out when you lift it. Cheap. All the side screws were loose enough my fingers could be used to tighten them.
Hooked up and lights went on then poof.
Works fine with my Marantz. This is junk. 3 weeks later they were selling a cheap set of speakers with it to try and move it.

Other Thoughts: I have been a Pioneer man all my life. Elite series going back to the SX1280 which I still have and have recently used the pre-in to use its large amp for a sub.
Hurts to see quality go downhill so bad. Pioneer used to be a respected name. Even the Elite units dont stack up anymore
I would not touch another Pioneer unless it was a store unit that has been proven to last a few weeks burning in.

4 out of 5 eggsGreat AV Receiver

Pros: The sound quality is very good, loaded with HDMI inputs, network functions work great. Airplay is a great feature, Internet radio is awesome and has an impressive selection of radio stations. The Pioneer control app works great on my ipod.

Cons: The on screen interface (home screen) for setting up the receiver is really bland and basic. When you consider all the effort put into the controls and function of this receiver, Pioneer went really cheap and dirty on the menus. It works fine, just looks cheesy.

Other Thoughts: The operations manual included on the CD does a really good job of explaining how to set up and control the receiver. I imagine that many people will find it a bit intimidating because of the large amount of information provided. Be patient and read through it and you will have a much easier time setting everything up. It isn't nearly as hard as some reviewers have made it out to be. Overall this a great product from Pioneer.

3 out of 5 eggsHot and Cold

Pros: Many options, and it sounds terrific. Once you get it set up to your liking, you will be happy.

Cons: (Can't swear in reviews) - the menus. I am a techie, and setting stuff up just shouldn't be this hard. Buttons on the remote that, when pressed, give no response, because they are context sensitive and you are in the wrong context. Once you figure out how to display a menu, you're presented with 1 option - an acronym and the choice of on or off. How about, at minimum, tell me what the (can't swear in reviews) acronym is? I've been at it for hours over the last 10 days. My Boxee Box sounds and works great, as does my BluRay player. Still can't get sound from TV-->receiver. Setting up AirPlay is not _complicated_ per se, just needlessly complex. I remember setting up audio and video in very early versions of Linux being this arcane. I hope someone at Pioneer drops some firmware effort into this receiver, because the hardware is great.

Other Thoughts: I have no doubt at all that, once I get this set up completely, I will be pleased. I will not update the stars because it just shouldn't be this hard to get it there.

4 out of 5 eggsGreat product so far

Pros: plenty of HDMI inputs
great sound with cheap speakers (better ones on the way now, using my old Aiwa speakers paired with a 12" Klipsch sub, 2 F-20 floor speakers on the way)
Airplay is great now that my network issues are resolved
zone 2 will be a nice feature once I add some outdoor speakers to my patio
the control app works pretty well, Would be nice to be able to select what zone to play audio through.

Cons: only 1 optical and digital coax in
HDMI control doesn't seem to work terribly well, though maybe better if I was connecting everything via HDMI
GUI isn't very nice to look at, including the internet radio/pandora/airplay screens
preset EQs don't sound very good so far (advanced game, rock/pop etc) most seems to have too much echo and treble.

Other Thoughts: Right now only have a 2.1 hooked up to this system but it does quite a nice job. I had a hard time getting it to actually play bass through the sub, finally figured out I had to change the front speakers to "small" instead of "large".
As mentioned HDMI control doesn't seem to do very well, but I'm running HDMI from my devices (blu-ray and DVR) straight to the TV then optical and digital coax to the reciever.
