i've bought this projector yesterday for my living... i come from a Onkyo 705+polk surroundbar+polk subwoofer.
My living room is 5 meters for 7.. most of all i changed to remove most of the cables "on air" and with no possibility of installing a real 5.1 cause my wife

The sources connected are a ps3, satellite tv and WDTV live for 1080p movies only..
the price is higher than others bars, here in Italy is 800 euros, while others are average 400 euros... i was intended to buy Ysp 4100 or 5100, but the extra 300-500 euros for those ones made me desist.
i read someone saying this bar had 4 hdmi in, that is true for ysp 4100 or 5100. we've got 3 hdmi 1.4 in and 1 out, that is good for people with 3d compatible tv , my screen is a Pioneer 4270, so i'm ready for a future upgrade. The 4100 and 5100 are now 3d compatible with new frmware, but only for video, ad the hdmi 1.3 don't permit the manage of the audio 3d.
My impressions now:
the auto-setting is very fast, at most 3 minutes, but not precise, i suggest changing manually the parameters for better results, especially for the back surround and with rooms not regular in shape.
the sound, that is more important.. the 5 beams work well, with good localizations of the surround sounds, an improvement to my previous bar.. this one sounds clearly and, thank to the subwoofer that "enters" when we need the right power, powerful.
i listen to movies at max 50 on 99 audio volume, and the walls often dither..
even with high volume we have no distortion, with clear voices in the front and no special effects covered in the surround.
Even trying some stereo material, as music videos and satellite radio, the listening is satisfying, not for audiophiles with great expectations but for the average listener good enough.
the look is great, and the sub even if powerful is so small you can put in design furnishing. For my tranquillity and my wife's happiness!

In conclusion, as all you know real 5.1, not considering real 7.1, is far better than these projectors, don't hope obtain the same results..
assumed this, i think this projector is worth the extra bucks of the other bars, considering i've listened to pioneer 3.1, panasonic and samsung bars and the one i owned till yesterday..
if you don't like (or your wife...) wires or cables of any type, and wanna good sound and "almost" 5.1 good sound for your blu-ray films, this is the one to go..
