US tech master MartinLogan specialises in electrostatic speakers – which means that instead of circular woofers and tweeters, as found in conventional loudspeakers, they use a micro-thin, curvilinear panel charged with electrical current to vibrate the air. In other words, they use state-of-the-art electronics to make speakers that not only look good but sound good, too. The Summit X is the ultimate expression of electrostatic technology, and a pair will set you back £14,998.

MartinLogan is exclusively sold in the UK by Absolute Sounds. 020 8971 3909;
