I have one of the older (pre-hdmi) ones and honestly, it does a fantastic job simulating surround sound. I got lucky on ebay when trying to find a soundbar for our bedroom. Had a sony HT-CT150 and it was awful... unless you like the sound of speakers in a coffee can. The geniuses even put the IR receiver and display on the sub. You know, the thing you want to hide in a corner and not see? Yeah... there. I didn't really think it through. In the store, it sounded the best out of 4 or 5 others in the same price range and had the most connections. I didn't realize the IR was on the sub until I had it home and installed. I lived with it for a year or so and sold it to a friend for $50.
I got lucky and won a Yamaha YSP-1000 on eBay for $150 shipped. I had remembered being pretty impressed with one like it (but with HDMI inputs, YSP-4000 I believe) a few years prior and figured why not bid. I half expected it to not work when I got it, but it looked ok and worked perfectly. Was surprised at how much it weighed, very heavy. I plugged in the YPAO mic and let it do it's thing with the mic where our heads would be. It's uncanny how well it processes the sound. The front sound stage is pretty wide, center channel is nice and clean/clear sounding and with our heads against the opposing wall, the "rears" sound very definitive. I have our xfinity x1 child box via coax and a sony blu-ray connected to it via TosLink to play our movies off the network or netflix and we use it quite regularly. Since it's a bedroom device, I did pick up a cheap 100W sub for it, but I never turn it on. It has enough depth for TV watching as it is without having booming while we are trying to sleep or relax at night.
I'd have to expect this new version of it will be even better. Granted, I doubt I'd spend $1000+ on a sound bar myself... but for those that are skeptical, in a fairly square room, it does a really nice job. Ours is mounted about 4.5 feet off the floor so it's about level with our heads and the TV is above it about 15 inches angled down with the dvd/cable box between them. The wall behind it is windows with rubber backed blackout curtains, left wall is flat drywall with a large mirror and the right wall is all wooden solid bifold doors. On center, it's about 6 feet from the left wall, 8 feet from the right, 4 feet from the ceiling and 9-10 feet from our headboard which is against the flat wall. Ceiling is also drywall and the floor is carpeted.
