Compared to last year's models:
Slight cosmetic change. VSX-1023 pictured above, but all four models look similar.
Amplifier sections same as last years models.
4K support .
MHL support for front HDMI inputs (except VSX-523)
Analogue just barely hanging on now, even non-HDMI digital audio inputs are down to a minimum.
VSX-1023 is a bit odd. It gains a component output since last year, which makes no sense to me. Last year both the 1022 and 1122 and inputs only, this year the 1023 adds an output, but the 1123 doesn't.
VSX-1123 / Elite VSX-70 are the only interesting ones. New features from last year include
4K Upscaling, not just pass-through, using unidentified QDEO processing.
Video on zone 2 (composite + stereo)
HDMI to extra zone.
Pre-out for front left and right channels.
