I know, this is a little like comparing apples to oranges, but I have kinda narrowed my soundbar search down to these 2 and looking for some opinions as well as feedback on my 'perceived' pros/cons list. I did consider and listen (in store) some others, and have been in research mode for some time, but just learned that my local store has 20% the msrp/common online prices thru Sat, so may have to push myself to make a decision... If it helps, my TV is new LG 55lw5600, only dabbling in 3D so far, but may do more in the futre as more 3d Blu-rays come out.
Part of my confusion is trying to decide between the Energy's bar with the amp, etc... built into the bar and not having to run speaker wires at all. Nice clean installation but are you giving up something compared to the Yamaha's receiver/amp unit? Seems like you are getting better quality speaker components and sub with the Energy system, but relying on whatever am is built into that small bar...vs. better quality amp and HDMI switching with the Yamaha but one-way, less capable/accurate speakers in the bar. Am I looking at it the right way? Here are some pros/cons as I see them...
Yamaha YHT S400
+Dedicated / sep receiver unit with FM, may not use much but nice to have.
+HDMI switching to only have one HDMI to run to wall mounted TV.
+No floor sub to worry about where to put
+3.1 rather than 2.1
+No lights on bar to possibly distract in dark room
+No power supply running to main bar, just speaker wire.
+Video, music, etc choice
+Price, similar to smaller Energy and $170 less than the larger Elite model
-Questionable bass output from the combo unit, althou sounded better than expected in store even in large open environment.
-Bar is smaller than I would like at 31" wide, will look shrimpy under my 55" LG led TV?
Energy Elite Powerbar with wireless sub
+Klipsch parent company, speaker components are from a speaker company, not electronics company
+True 2-way setup with mid-woofers
+Larger bar size at 40" to look better under the TV
+Wireless 10"sub, can only assume will make a difference with 3d blu-rays
-No HDMI switching, must use optical from TV
-2.1 rather than 3.1, although not sure I'll miss the center speaker
-Pricey, even with 20% off it's $170 more than the Yamaha
