Hi-fi amplifiers

The 840A can form the hub of a simple multi-room system and features balanced inputs and a monster power supply

One of the cleanest, most informative amps available below the three grand mark

If you want every tune to cuff you across the cheek, then the Cyclone might be the amp for you – but it's not an all-round listen

Cambridge, pretty much the master of budget hi-fi at the moment, adds another superbly good and cheap piece of kit to its already bulging stable

The build is as reliable as ever. The sound however falls way below the usually high standard we have come to expect from Denon

The Supernait is arguably the most versatile amp Naim have come produced, a hefty price tag, with some sonic flaws, but still very impressive

When it was released, the Fatman docks were very orginal iPod accessories: the valves and chrome are fairly commonplace now, but they're still a draw

Specification and design impressive apart from the remote), but perhaps lacking substance at this price point?

Has a welcome, grown-up sound that's effortlessly musical but it doesn't like to get down and dirty

Convincing digital amplifier, quality build but perhaps for the price we might expect a little more body and warmth
