Pre/Power Amplifiers

You gotta love items with absolutely perfect names: 'Land Rover Defender', 'Rolex Explorer', 'Fender Jazzmaster'. When founder and chief engineer, Dan D'Agostino, dubbed his assault on the high-end 'Relentless', with cost-no-object flagship monoblock power amps [HFN Mar '20], he might have been referring to himself, as that is how he approached the task. With this matching three-chassis Relentless Preamplifier (£159,500), he's raised the bar once more.

Upon my taking delivery of the review samples of Da Vinci, about which I was warned in mid-summer 1991, company founder Antony Michaelson launched into his usual tirade about the high-end, with barrels of venom for American ballbuster amps in particular.

The development of this completely new power amplifier has been a major undertaking for Naim. Up to now, its designs have been variants on the late Julian Vereker's founding concept, which led to the first NAP 250 stereo chassis some 25 years ago. Even now, the company's biggest current model, the NAP 135, is a monoblock variant of the '250, with more generous power supplies allocated to the separated channels.

It used to be said that the only true way to learn was to find out something for yourself, then it will stick when all book-learning has long since been shed. This was drummed into me when I was working on the development of LEDs (green ones, to be precise).

To misquote Sly & The Family Stone just a little, Swedish hi-fi company Engström – it only makes tube amplifiers – is a family affair. Founded by engineer Lars Engström and his industrial designer nephew Timo as recently as 2008, the company is based in Lund, just northeast of Malmö, and has its R&D HQ some 600km away in Nacka, south of Uppsala on the Baltic Sea coast. The division of labour in the company sees Lars Engström as chief engineer, having given up work in fields as diverse as navigation, microcomputing and railway signalling systems in 2001 to concentrate on amplifier development, while his nephew is responsible for the look of the products, and the company operations.

It's the style of the Boulder 1100 series amplification that grabs you first – very different from the common image of US-made high-end hi-fi, even if the £30,000 1160 stereo power amp lives up to at least some of the stereotype with its 61.2kg mass. Instead of the usual scattergun buttons, grab-handles and menacing – not to mention finger-slicing – heatsinks so common in products of this type, seemingly built with no concession to domestic acceptability, the Boulder power amp and its matching £22,500 1110 line-only preamp have a much softer look.

Never let it be said the product name isn't long enough – in the 12 years since Naim launched its network audio all-in-one, to which the buyer need only add speakers, it's grown from the simple NaimUniti of the initial model, all the way to this, the £2399 Naim Audio Uniti Atom Headphone Edition. And yet here, less is more.
