is the state of the art?

As you can read here already, you can not make via HDMI but only with composite (RCA video) the default setting.
The OSD menu is not reminiscent of Atari / Amiga / C64, no, actually, the video was better.

The device is low but anyone who thinks he can install it in a TV rack, made a mistake, because - at least for me - after a moment the message is TEMP and then OVERHEAT, so do not go, because too little cooling.

The setting options are. , , ., Who needs it?
but
Bass + -
Heights + -
Balance RL
One looks in vain.
Front only one adjusting knob for volume, balance on menus.
Unit was low, so I'm keeping it.

To allow all devices via HDMI pass through the Pioneer is in practice not a deal breaker.
The possibility to connect more than one device only via optical inputs do not exist.
