I purchased this receiver Thursday from Best Buy. It's being used in my master bedroom with Energy 5.1 Take Classic speakers. My receiver in the living room is a Sony STR DA-5400ES, one of Sony's top of the line receivers from a few years ago ($1000+). Compared to the Sony, this receiver is holding it's own. The sound is excellent and the iPad experience is way too cool, they have really done a nice job.
Currently I have an HTPC and a SqueezeBox Duet connected to the 1021. I found this thread searching for a way to listen to music from the SqueezeBox while viewing the HDMI video signal from the HTPC. I discovered the post about the "Signal Sel" button on the remote and all is good now. However, in my opinion, the ability to select a video source and an audio source is a very basic function of a receiver and Pioneer should make this more discoverable. At a minimum, it should be available in the input edit screen.
I have tried all functions/features of the receiver and all have worked well for me. I see absolutely no video artifacts vs. my Sony receiver as a few others have mentioned.
Not sure if others have seen this, but I have to reboot my iPad often to get the iControlAV2 app to reconnect to the receiver even though I can ping the receivers IP address and it is definitely on the the network and accessible from other devices. Also, when I use the iPad app to the turn the receiver off, the app immediately displays an error and I must turn the receiver back on using the remote. THEN, I discovered the Network Standby setting in the Network Setup section. This is off by default, but after turning it on, the iPad app stays connected when the receiver is turned off and I can use the app to turn the receiver again. We'll see if this helps with the frequent iPad restarts. Seems like ON would have been a better default value for this setting.
The absence of the volume indicator output to video is missed. Also, the 1021's OSD disconnects the current HDMI signal to display the menu. The Sony displayed the menu overlayed on top of the current video signal. I know the 1021 is dropping the current HDMI signal because my HTPC is dual monitor and when displaying the menu the desktop switches to the second display.
Those are my only minor complaints. For the price and feature set, I am very happy with the purchase. I hope Pioneer adds more functionality to the iPad app in the future.
