If you are looking to seriously enhance your TV sound then the Monitor Audio SB range of soundbars is the way forward!

Traditionally you'd need to use a large AV Receiver to power it, but this isn't always feasible so Monitor Audio have released their Dolby Digital Decoding amplifier that connects via Optical Input and can output a front left, centre and right audio channel.

This is perfect for TV rooms, snugs, kitchen televisions etc where good sound is important, but surround sound may be a bit excessive.
