It's a funny thing with sound that, and I only have a glimpse of understanding because both my brother and his friends do sound for concerts, is how undervalued it is. People spend thousands of dollars on Televisions and then aren't willing to dish out more than $200 on a sound system to go with it. Not realizing that part of what makes all viewing experiences engaging and why seeing something in an IMAX, typically, is many times better than a normal movie theater or at home, is because you have both amazing Visual and Audio components working seamlessly together.
Granted, I'm just as guilty of this because when I got my UN65H7150 (msrp $3,299.99) for $1500 at bestbuy I said I didn't want to spend more than like $250 on sound. Now after spending just $250 on the sound, its really easy to tell how drastically out of proportion the sound is to the viewing quality of the TV with the soundbar I currently have. Many people who do truly value the true aspects of sound, and correct me if I'm wrong, end up over the years assembling a system that is often times 2-5 times more expensive than the TV that is being used with it. Both my brother and his friend for example have over $3000 and $4000 respectively in audio components alone that are hooked up with TV's that cost under a $1000. And most of that money is spent into quality, not bass which is what most of the cheaper soundbars on the market are using as their main advertisement point.
The tricky thing after viewing many of the posts in this thread is people looking for cure all soundbar for under $250 or $500 or $750 which I think is a very difficult task after testing out many of the available options today. My favorite bar so far under $400 would be the Samsung HW-H550. This is the bar I currently have and I am relatively happy with it, minus how voices and dialogue get out of proportions to the sound and music at lowest listening volumes at night time. At mid to high volumes it's great, but not everyone lives alone in a detached house where they don't have to worry about waking up kids/neighbors/parents.
As Digital Rules suggested, for people like myself who live in a condo or apartment and who have neighbors, we aren't necessarily looking for room shaking bass. For this a possible better option is to look at stand-alone bars such as the Yamaha that Digital linked or maybe something similar to a Sonos but it's an individual preference of how each sounds. With my bar I have the sub turned all the way down to -6.
I had to go outside my initial price range, but for what I'm currently planning on picking up in a few days after it's back in stock is a $1599 bar that i got for $799 ($1999 msrp). The different between this bar and a Sonos playbar alone is mind blowing in the clarity of the sound it produces. Kind of a long post but that's my two cents on the topic and advising being to consider spending a little more to get a product that is going to make you smile after it's plugged in rather than something that is going to make you smile on the way home because you got it for under $200.
(There are probably numerous grammatical errors in here and I apologize (maybe even in this sentence lol). I'm sure I'll notice ten of them right after I post this and I'd fix them but I cannot edit my posts yet.)
