If you have it set up properly with decent balanced system it is a treat to take in a film or tv program with it switched on.
The average systems that come complete with a typical television installation are pretty pathetic,failing to decode the Dolby surround signal properly into its components of front rear and center.
Like hi fi there are good systems and and cheap nasty systems,A £1000 is a good budget level to find yourself with a system that does what it says on the tin.
As with an hi fi system treble or high frequency sounds say breaking glass crunching gravel on a driveway are the mjori parts of a sound to suffer,instead of nice clean treble you have a fizz or distortion that really breaks down your enjoyment of the sound.
Cheap surround systems really are a waste of time,and most of the Japanese units are very poor.If you do want a proper system to blow your socks then one word matters British,denon,always remember cheap price cheap sound.
