As big screens go, the audio performance of the 2 x 10W speakers is fairly decent. They have a broad dynamic range that makes dialogue easy to hear in most environments.
There are some useful audio features. SoundNavi is a function that configures the speaker control settings according to the setting, either on a stand or wall-mounted.
Dolby Volume evens out unwanted sudden changes in volume that can occur during commercial breaks and when switching between channels or sources. The screen also has Voice Enhancement, Dynamic Bass Boost and two surround sound settings, Spatial and Cinema.
It's worth tinkering with the settings, depending on what you're watching but a separate sound system is of course essential when watching a drama or movie.
In the 55-inch 3D LED sector you can pay £2,500 for Sony's stunning Bravia KDL-55NX813, £2,300 for LG's 55LX9900 or just £2,000 for a Samsung UE55C8000. Clearly the Toshiba 55WL768 is the least expensive model at £1,800 so represents good value - even if its connected TV offering is no match for its rivals.
If you're prepared to sacrifice a few inches and switch to plasma Samsung's excellent PS50C680 can be snapped up for no more than £1,000.
