My wife purchased one for her parents who are getting on in years. Since getting a Samsung LCD last year they have complained about intelligibility issues, She did some shopping around (at my suggestion) for a sound bar. She liked the idea of the under TV one box approach versus a separate sound bar / woofer, especially since her folks have the TV on a credenza. She did compare the Zvox (assume 580 because it was the $500 one) and found the SpeakerCraft to have much clearer dialog. Incidentally the spouse is a classically trained musician who knows what stuff is supposed to like. So I trust her judgement. The folks received the unit a few days before Christmas and are loving it - they live out of state from us so it had to be shipped. Apparently, it was also an easy install for them - PCM out from the TV into the box - done. OK so maybe not an audiophile review - but certainly a "real world" one.
