Sure, your 7.1-channel setup does a great job of swarming Maverick, Iceman and Jester's jets all around you, but imagine how much better it would be to get vertical surround effects as well. Pick up an Onkyo
TX-SR607 receiver (available next month for $599) and you can find out, thanks to its Dolby ProLogic IIz (DPL IIz) processing. Just put a couple more speakers high and tight above your front channels, hook them up and enjoy. Onkyo is kicking off the DPL IIz craze with the midrange TX-SR607, and will be rolling the feature out across its higher-spec models over the summer. If you're not so interested in more channels, even the more modest TX-SR507 ($399) and TX-SR307 ($299) models have been refreshed with a sprinkling of more HDMI inputs and support for HD audio codecs.
