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.

Analogue addicts find themselves with a bewildering array of choices that extends way past which turntable and/or tonearm to buy. The world of cartridges is complex and potentially baffling, especially with moving-coil types. Many eventually progress from buying the big brands to trying out specialist makers – and it's here that we find Lyra. Its products inhabit a niche within a niche: they are all hand-built, low-volume devices that for nearly a generation now have sold largely to devotees of the brand.

The original NAD 3020 integrated amplifier of the late '70s was a genre-defining product – a compact integrated full of useful features that cost relatively little and became recognised for bringing high-quality home audio to a much wider audience. I wouldn't mind betting that many readers will have owned one at some point or at the very least be familiar with its reputation as an 'all go, no show' audiophile amp for its remarkably likeable sound but rather retiring 'grey slab' looks.

Having been something of a ‘sleeper’ for a while, favoured by an admittedly growing group of computer-based audio enthusiasts, there’s every sign that Roon – the music server/database software – is finally going rather more mainstream. A number of manufacturers have launched products with, or updated existing models to, Roon-ready status, and now the company behind the software has entered the hardware market with a pair of hub components co-developed with Intel: the £1500 Nucleus, and the £2500 Nucleus+ we have for review here.
