Review: Andrew Everard

When it comes to affordable music players with hard disk storage, few companies have the pedigree of Korea-based Novatron. Its range of products, sold under the Cocktail Audio brand worldwide – including here, before a UK-only rebranding to Novafidelity – starts from as little as £650 for the X14 model. In this instance the user is able to decide how much storage capacity to have installed, or even buy the unit 'bare bones' and add their own choice of drive.

Of late we've had some speakers through editor PM's listening room only describable as imposing, but nothing quite prepares one for the sheer visual impact of the Duo Primo XDs from Germany's Avantgarde Acoustics. Standing some 1.8m tall by 67cm wide, and weighing 185kg apiece, installing them is a matter of slotting the boxes together rather in the manner of building a PA stack – an appropriate analogy, as we'll discover – while the price-tag is similarly huge, at £79,500 a pair.

Canadian company Paradigm makes no bones about where its Persona range is pitched: it describes it as 'The Evolution of Luxury', as you might hope of a lineup topping out with the 9H speakers at £34,000 a pair. In fact the Persona 9H is currently Paradigm's absolute top model, being the priciest, and technically most complex, design in the company's flagship range. Like the other Persona models it comes in a choice of five standard colours: Harmony White, Vanta Black, Carbon Black gloss, plus metallic Aria Blue or Sonic Silver.

Alot can happen in three years, and while the amplifier we have here is very much the smaller sibling of the DIA-400S [HFN Oct '16], it's also boosted by the inclusion of the Danish company's NPM module, a complete network audio solution giving access to a wide range of streaming options.
