Excerpt: This is the bigger brother of the DAV-DZ410, which received a decent four-star review in our May 2007 Supertest. So given that this has added HDMI and wireless rear speakers, why only three stars? For one thing, the 'DZ830's menu system is the same ugly, confusing mess as its sibling's. The auto-calibrator for the speakers is also fiddly to use and – when checked with a sound-level meter, rather inaccurate. Not like Sony at all.
Pros: Wireless rear speakers, good picture performance, stylish looks
Cons: Unexciting sound delivery, fussy infrared signal to rears, poor auto-calibration
