Sharp's previous LCD TVs haven't been particularly distinguished in the audio department. But the 46LE821E overcomes its slimness to produce sound that at worst is functional, and at best is really quite decent.
The mid range is pleasingly open-sounding, giving a degree of breathing room to action sequences, and there's a lot of treble detailing to be heard.
It's a shame this isn't counterpointed by a bit more bass power and depth, and there's a touch of distortion if you push the volume too high. But similar issues can be found with any number of other really slim TVs too.
On the one hand, Sharp has put a huge amount of effort into coming up with a genuine innovation that really advances the cause of flat TV picture quality.
But at the same time, there's no denying that the best part of two grand is a hefty amount to splurge on a 46in TV these days - especially when that TV doesn't have 3D support.
In the end, going for an average 'three' score seemed the most appropriate response!
