Fatman iTube 452 review

Fatman is, perhaps, best known for its compact valve amplification, often seen at A/V shows and dealers with Apple's iPod close by.

The company has become synonymous with valve-based docking stations and brought 'analogue' to the diminutive digital device, but now it has upped the ante with a £1,500 no-nonsense valve amp.

Traditionally, Fatman products have comprised a dock with a small valve product attached, but the iTube 452 is different. The designed in the UK, made in China, 45-watt per channel, full-sized integrated amp is beefy enough to stand on its own.

As such, it's conceivable that people will buy one on the basis of its audio performance and may never even take the iPod dock out of the box. It joins – at the top of the tree – the iTube ValveDock, iTube182 and 252 as standalone (read: speakerless) amp and dock systems; the range-topping iTube Mothership preamp and monoblocks are bigger still, but the flagship lacks the iPod docky component.

Classy design

The amp is certainly cute. Resplendent in rich black matt paint, with a piano gloss top-plate and a layer of gold finish beneath the valve cage, the half-moon-shaped amplifier really looks the business.

The valves (5x 12AX7s in the preamp stage and two pairs of self-biasing 6L6's in the power amp) are inset into the brushed-gold finish, which makes extracting the preamp tubes next to impossible, but gives them a low profile.

This low profile is also aped in the source selector and volume control, which are on the glossy black top-plate. A VU meter on the front and a power switch on the right side of the amp complete the deal (a remote control comes with the unit, but don't get your hopes up – it only drives the dock).

Behind the four equally sized potted transformers lay four sets of phono sockets, an IEC socket for mains and two sets of speaker terminals. These have separate taps for four and eight-ohm loudspeakers and getting the impedance right does make a small difference to the sound. If in doubt, use the eight-ohm tap (better yet, experiment).

Read the Manual

Repeat this like a mantra – Read The Ruddy Manual – because here it makes the difference between a perfectly working amp and replacing 13A fuses at a fair lick. The manual states the amp needs a five-minute cool down between power-ups. Miss this at your peril; the tubes will survive, but it will protect itself by taking out the mains fuse. We went through four mains cables before falling back on the manual.

Similarly, the dock will power up (from its own plug-top power supply) and then turn itself off in a second, unless you turn it on from the remote and only the latest manual will tell you this. The latter does seem to be a limitation, though; a dock should spring to life automatically, not wait to be awoken by a gold handset.

On the subject of design, there seems to be a clash here. The predominantly black and gold, curvy amp is at odds with the black and chrome, angular ValveDock and the remote looks like it belongs to the amp, not the iPod product.

This is not a big clash and is only skin deep, but there's not much in the way of family design, in the way other Fatman products mesh together. Part of the reason for this is the dock is common to the basic iTube, the iTube 182 and 252 amps, all of which are styled more in line with the 'ValveDock' (there are no valves in the ValveDock).
