Price well - power well

After much back and forth, despite the moderate reviews I have now risen with the HW-H7501. I have a TV to UH55HU8590.
Both are mounted on the wall, and I still have not found the correct settings. Sure, you can not compare this Soundbar with a proper sound system, even not at this price, but this should be for normal people like me enough.

What I think is great:
- Class Design, adapts the 55HU8590 class at the Curved.
- Subwoofer without wires! One can stand it where you like.
- Attachment to Samsung TV easily and quickly

What bothers me:
- I am still the best settings which you have set? We read a lot of SW -6 and so
- Sound can be described bad acts partly spurious.
- Connections: Only 1 HDMI input for external devices.
- Switch to other channels with the soundbar remote control possible, why can not here do not use the remote control Samsung ??? !!!!!
