Review: Mark Craven

In this era of all-in-one amplifiers and ‘crossover’ products, where even a tube amp might come to market with a built-in USB DAC, there’s something refreshing about Californian brand Pass Labs. Now approaching 35 years in business and named after founder and chief designer Nelson Pass (also the man behind Threshold in the 1970s), the company has long been known for its focus on frill-free, performance-first designs.

Balanced Audio Technology, otherwise known as BAT, doesn’t beat about the bush when it comes to its audio philosophy. The main page on the US manufacturer’s website lists core principles, all of which have an engineering bent: ‘balanced is best’, ‘dual-mono construction maximises performance’, and ‘zero global feedback achieves natural sound’. All three of these are at play in the company’s VK-90 preamp.

Hegel is fond of its idiosyncratic product names. In 2023 the Norwegian brand felt confident in christening its new CD player the ‘Viking’, ignoring a model number altogether [HFN Sep ’23]. In the same year it also launched the P30A preamp and H30A power amp [HFN Jun ’23] – separates also known as the Conductor and the Orchestra, respectively. 2024 saw the arrival of the H400 integrated amplifier [HFN Oct ’24], aka the Streamliner due to its networking features, and now we have the new D50, a DAC that Hegel says is ‘affectionately named the Raven’.

If I had a pound for every time I’d heard someone talking about WiiM in the last year I would easily be able to afford the £329 streaming amplifier auditioned here. Since its arrival in the UK in 2023, WiiM – the consumer-facing brand of California-based smart technology company Linkplay – has earned a reputation for compact, networked hi-fi products that combine wide feature sets and a forward-thinking control app, but at prices that would have seemed like science-fiction just a few years ago.
