Integrated Amplifiers

Sleek design, comprehensive functionality and even a built-in wireless DAC make the AS-400 a thoroughly modern integrated amp – for today’s iTunes generation Not long after the introduction of Micromega’s £2800 integrated amplifier, the IA-400, and its £1100 WM-10 wireless-equipped DAC comes a component that effectively combines the two: a new version of its integrated amplifier (with ‘AS’ instead of ‘IA’ nomenclature) featuring a built-in 802. 11n Wi-Fi receiver/DAC, working to Apple’s latest AirStream protocols. As with any wireless connectivity – Bluetooth or Wi-Fi – there is something quite spooky about the ability for music stored on computer, mobile ’phone or PDA to be played through one’s hi-fi system as if by magic. Unlike open source DLNA/UPnP systems, however, AirStream (formerly called Airplay) is proprietary to Apple and works only with its iTunes media player, iPhones, iPads and the web-enabled iPod Touch.

I find it very odd that the M2 is the most technically advanced and subjectively successful digital amplifier yet to grace my listening room. Until recently, right now in fact, NAD was not a company likely to spring to mind for its cutting edge technical innovation. The brand saw me through my penniless student days with a host of hi-fi products that majored on simplicity, great value and a remarkable immunity to spilt beer. But the M2 is very different.

As far as expressions go, a novelist would describe it as ‘eyes agog’: that’s the look that crossed my face in January 2009, at the Consumer Electronics Show in Las Vegas. It wasn’t even an actual piece of hardware that grabbed me. It was a preliminary product sheet, a flyer for the forthcoming Quad II Classic Integrated. Talk about a well-kept secret: even the normally voluble Tim de Paravicini, who designed it, let out nary a peep [see p110].

Surfing the wave of new and innovative Far Eastern valve products, Emillé looks set to ride a tube of its own with the visually stunning KI-40L. The Far East has been producing quality components for many years (see boxout for company history). However in recent years, as the world has shrunk thanks to the internet, an opportunity has opened up for us to try exotic fare on offer from the likes of Shanling and now Korean company Emillé. Part amplifier, part sculpture this physically imposing component is rated at just 40W/ch and forms part of a five-strong range.

Having played with a number of PrimaLuna ProLogue products, I’m safe in saying that each and every one represents astonishing value because 1) they’re made in China, but 2) to European standards. They single-handedly established and provided credibility for the lower entry-level price point for rock-solid valve products, and showed that China was ready to compete with the rest of the world in hardware manufacture, if the proper structure was applied. With DiaLogue, PrimaLuna is attacking the next price point, with the same vigour. That in itself should be enough to make the DiaLogue Two a fascinating prospect for those with up to £2000 to spend on amplification.

I always get a warm, Sunday afternoon feeling when a new product arrives from Arcam. While you can imagine the Far Eastern competition frenetically working 24/7 to be first to market with the latest multichannel widget, I see Arcam as a little more reserved, a little more British. The AVR600 may have been a long time coming with its HD-audio decoding, multi-room installer features and premium video processing but it simply exudes dedication and polish from the moment you open the box. It’s substantial for starters.

Yamaha’s Z11 is an amplifier of extremes. Almost every feature can be prefixed with terms like ‘most’, ‘advanced’ and ‘leading’ and the fit and finish is superb. The specification sheet is impressive and the features list is the size of the Encyclopaedia Britannica and reads like my very own wishlist of AV technology. The Z11 is right at the cutting edge of multichannel audio, HD video and multi-room technology and then goes on to incorporate a level of audiophile engineering that would compete favourably with high-end two-channel components.
