When Onkyo announced the TX-SR607, the company made a big deal that it was the first AV receiver to include onboard Dolby Pro Logic IIz processing. Dolby's new format relies on "height" speakers--two satellite speakers situated above the standard front right/left speakers--to create a more "airy" soundscape--or at least that's the idea. We tried our best to enjoy the extra atmospheric effects, but the reality is our ears had a tough time hearing anything beyond placebo effects. But honestly, who cares? The Onkyo TX-SR607 is a great midrange AV receiver without Pro Logic IIz, offering up six HDMI inputs and excellent sound quality at a street price that is already down to $500 online.
If you're looking for more video-centric features like a graphical user interface or high quality analog video upconversion, it may be smart to hold off until theand are released. But if you'd rather maximize your HDMI connectivity and sound quality on a budget, it's tough to beat the TX-SR607.
