Integrated Amplifiers

In celebrating the company’s 60th anniversary Nagra’s specialist hi-fi division pays homage to the ‘king of tubes’, the timeless 300B triode, in a new stereo amplifier 'A key difference between consumer electronic components manufactured for hi-fi systems and professional products made for sound engineers is the fact that you can drag pro gear across a room by its mains lead without it breaking,’ quipped an industry veteran to me, way back when. Witticisms like that, noted during formative years, tend to remain embedded in one’s memory banks for life. As does the iconic Nagra marque. Think Nagra and you think Swiss precision engineering at its finest: electronics made for professionals.

The new Primare integrated introduces a bespoke class D module Sweden’s Primare company is renowned for its chic ‘designer’ components with immaculate alloy fascias and classy stainless steel controls. This I32 integrated is more than just a makeover of an existing design, however, as it employs the latest generation of Class D switching modules introduced in Primare’s multichannel AV amps in 2008 – dubbed ‘Ultra Fast Power Device’. The I32’s preamplifier section has a dedicated power supply and is isolated as far as possible from the two UFPD modules. As high efficiency is a given with Class D designs, here is an eco-friendly amp you needn’t feel guilty about leaving in standby, as it draws just 0.

An innovative amplifier featuring sophisticated adjustable impedance matching. From the outside at least, what we have here is an integrated amp seemingly conventional in most respects, though its dimensions are just 440x80x410mm (whd) meaning it takes up no more shelf space than would a small turntable.

Revisiting the first British solid state amplifier Goodmans was one of the most prolific loudspeaker makers of the 1960s, also supplying the radio and television trade. The company ran from 1932, ending when the TGI group was broken up in 2004. But the brand name as such survives marketing a range of DVB set-top boxes and LCD TV sets. Introduced in 1966 with a price tag of £49 10s, this compact little amplifier, the Maxamp 30, measured just 10in tall, 5in wide and 7in deep.

Emblematic of the evolution of the Chinese-made valve amp is PrimaLuna's ProLogue Premium - in case you hanker after a value-for-money integrated with no rough edges This year, my son turned 21 and graduated from university. That was enough of a reminder of time’s passage to depress me. Far less cataclysmic an indicator was another shock to the system (metaphorical, I stress) in the form of the PrimaLuna Prologue Premium Integrated Amplifier. It’s not that the original, which ‘legitimised’ Chinese-made valve amps for Western consumers, was shabby by any means.

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.
