Review and Lab: Paul Miller

At a time when every new high-end product seems to come with an extensive backstory, the legend behind the 'aspen' FR30, the first speakers from Colorado-based PS Audio, still takes some beating. The £28,000-a-pair floorstanders have, we're told, been '50 years in the making', which places their beginnings just before that of the company itself, started by Paul McGowan and Stan Warren in 1973. In between times, McGowan left, worked with Arnie Nudell of Infinity Systems and then bought back the PS Audio name in the late 1990s, becoming its CEO. So we can safely assume that what is now realised as the aspen FR30 has been in the works for all that time.

Only one issue ago we reviewed an interconnect cable whose core thesis focused on achieving a low capacitance and dielectric loss by utilising an 'air' insulation. That was Kimber's new flagship 'Naked' interconnect – a cool £12,700 per terminated metre [HFN Mar '22]. Somewhat more affordable, but also leveraging the 'air dielectric' theme, is the NF-204 Micro Air interconnect from Germany's most prolific cable manufacturer, In-akustik, based in Ballrechten-Dottingen.

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.

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.
