In recent years, LG has developed into a brand to be reckoned with, not least because its LCD and plasma flatscreens have been critically lauded. LG have also brought us products in many different sectors of technology, including the new HT903TA home cinema speaker system to compliment it's flatpanel TVs.

However, speaking to the company some time ago, it was made clear to me that the brand recognised an inherent weakness with its flatpanels – indeed with thin TVs in general – which is that they don't sound very good. With this in mind, LG have designed the HT903TA to address this weakness.

This weakness goes beyond the criticisms that can be levelled at their performance with Dolby or DTS soundtracks, and way beyond the fact that many suppliers foolishly seek to synthesise surround sound from just two or three speakers.

The problem is more fundamental: that flatpanel TVs are simply the wrong shape to perform respectably as loudspeakers – and the resulting sound they make is coloured and, usually, lacking in clarity and intelligibility.

Levinson design

Boffins from LG told me they understood the problem, and resolved to do something about it. The most dramatic demonstration of this good intent was to co-opt one of the most famous of all audio designers to fine-tune some of its products, namely the eponymous Mark Levinson, who once owned a company of the same name – now part of the Harman group.

But is this more for show than a practical measure? I would argue that the LG products that bear the Mark Levinson imprimatur, including the LG HT903TA system tested here, are Levinsonesque in name alone – as anyone who has used the real thing can testify.

Still, LG has some other bright ideas up its corporate sleeve, of which the HT903TA is a good example. It's a full-on, all-singing, all-dancing home cinema system that includes a DVD player (not Blu-ray, although in principle a Blu-ray player could be plumbed in via HDMI); a 5.1-channel amplifier with all the usual surround decoders; and a full 5.1 set of loudspeakers – a centre, speakers for each corner of your viewing room and a subwoofer. Given its job description, it costs surprisingly little at around the £290 mark – give or take the odd groat.

The system comes in an unfeasibly large outer box, but when its contents are decanted, you find a remarkably complete package, with science applied to keep everything neat and tidy. What looks at first sight like a slimline DVD deck turns out on closer examination to be the amplifier/DVD player.

If it all looks a tad too dinky to be convincing, it's because the normally large, heavy and hot-running amplifier is fully digital.

The main speakers are floor-standing columns, roughly champagne flute-shaped (but somewhat different from those in stablemate system HT953TV), and complete with pedestal stands, which are heavy enough – just – to confer reasonable stability, though homes with small stampeding toddlers should take suitable precautions. These speakers are not hard to tip over...

The system has some useful refinements. A built-in FM tuner gives good sound quality in stereo, and video upscaling to 1080p is available from the internal DVD player via HDMI. The system will even run from a USB source – an MP3 player or an iPod.

Surround sound comes courtesy of Dolby Digital and DTS, Dolby Pro Logic II and a 10-channel surround algorithm from LG itself, called VSM (Virtual Surround Mode – 'virtual', of course, a synonym for 'not').
