Pre/Power Amplifiers

Nagra has, with the exception of the now-best-forgotten Pyramid amplifiers [HFN Feb ’05], a near-faultless track record. When you consider that the company leapt from professional tape decks to audiophile-grade valve electronics 20 years ago, the transition has been remarkable. With the second of its HD models, the HD PREAMP (joined by the HD DAC), one witnesses the completion of ‘Phase One’ of Nagra 2.0.

It’s often said that less can actually be more. For example, many high-end hi-fi products are devoid of fripperies because the lion’s share of the build budget is spent on the bits you can’t see, such as high quality components. This in turn gives better sound per pound, or so the theory goes. Yet other designs come festooned with features and often lack ability in the sonic stakes.

Obviously not afraid of a spot of (Russell?) crowing, Oslo-based Hegel describes its new Reference H590 integrated amp, just going on sale at £9000, as ‘Master and Commander’. Apparently it’s ‘A master at musicality’ and ‘The commander of any set of speakers’. Mind you, you might be tempted to forgive the company for its exuberance – after all, the new arrival is something of a monster, standing an AV-receiver-challenging 17.1cm tall, tipping the scales at 22kg and delivering over 300W per channel. Well, 301W a side actually, according to Hegel, making it at least 50% more powerful than its previous top integrated, the H360.

A genius mix of both rebellion and restraint, Audio Research's latest chapter in the Reference saga, the REF160M monoblock power amplifier, is one of the biggest departures in the much-lauded series' evolution. Most obvious is the new look, which takes its cues from the G-Series, bringing with it a cool oversized meter, but the rest of the amplifier has been redeveloped, too, not least to incorporate features that will improve system matching, reliability, ease-of-use and initial set-up.

Look at the photos: the Nagra HD AMP's slim, vertical layout will remind fans immediately of the company's first power monoblock amplifier, the VPA. This vertical stance is not all that common – remember Halcro? – while the small footprint it affords makes a vertical model instantly appealing for those who value floor space. Nagra's new, top-of-the-range unit, however, is purely a solid-state device which – profile aside – is the antithesis of the all-valve VPA, which was rated at 50W in 'Pure Class A'.

How sad. Last year was the 70th anniversary of the founding of Crown, and the event seems to have gone unmarked. The only notable occurrence was that its parent company, Harman International, was acquired by Samsung, which is a rather forlorn way for this most American of brands to celebrate seven decades.

So, it's a slimline amplifier, and it's French – already thinking of the 'D' word? But while it might seem that the M-One amplifiers from Micromega could be 'inspired' by the success of Devialet's range, in fact they have little in common beyond their country of origin and a passing resemblance in dimensions: under the skin they're very different animals.
