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.

Does the world really need another high-end turntable? That’s the question Brinkmann’s Spyder has to answer, because there’s already a surfeit of fancy vinyl disc spinners sitting pretty in this high value market. This deck needs to be special in some way then, and so it proved. Costing £9795 in basic form, it’s one of two belt-driven decks in the German company’s range of hi-fi separates, sitting alongside the Balance 2 [HFN Jul ’14]. Brinkmann also makes the Bardo and Oasis direct-drive turntables, which themselves are interesting and innovative things.

The Progression Stereo amplifier is built around a dual-wound 1400VA toroidal transformer coupled to 400,000µF of power supply storage capacitance that feeds no fewer than 48 power transistors – 24 per channel. On paper this is said to generate 300W/8ohm, doubling into 4ohm [see PM’s Lab Report]. And it’s yours for roughly half the price of a pair of the company’s Progression Monoblocks [HFN Jun ’17].

In the early days of hi-fi, the budget amplifier was usually considered an object of disdain, to be quickly upgraded as soon as funds allowed. More capable designs such as the NAD 3020 changed this view and by the late '70s improvements in component technology had made it possible to produce really good amplifiers that still could be sold for reasonable prices.
