Looks can be deceiving, especially if you first see a Continuum Obsidian turntable and Viper arm fully-assembled. Its three-legged, dust-coverless design recalls innumerable open-plan decks from affordable up to high-five-figure absurdity. Then you note the Continuum's price tag and realise it's of the latter: the Obsidian sells for £39,998, the Viper £11,998. Generously, you can save a grand buying the pair for £49,998.

While it could never hope to match the seemingly annual product replacement cycle of some mass-market brands – and nor, I suspect, would it care to – Naim still maintains a continuous programme of product development that goes on 'behind the scenes' of some of its more attention-grabbing launches. So while all the big news from Salisbury has concerned network-capable audio, as Naim rolls out its 'Future Platform' from the latest Uniti products to new ND-series network players [HFN Apr '19] and second-generation Mu-so models, in the background the company has been working on its core integrated amplifiers, the Nait series.

I think I can be pretty confident in saying there aren't too many new British hi-fi components out there whose development has been government-funded. Clearly they do things differently in Germany, where the Federal Ministry of Economics and Energy underwrote the design and development of the network-capable DAC/preamp forming half of the subject of this test, T+A's £23,400 SDV 3100 HV. The project has borne fruit in the behemoth of a digital converter you see here, all 26kg of it, described as a 'Super High Definition Audio DAC with bit-perfect data transmission and resolutions of DSD1024 and PCM768'.

Imagine that instead of each of your stereo loudspeakers sitting in splendid isolation, optimally aligned with respect to the listening seat, there was a large band of metal or plastic curving between them, joining the two cabinets. If you know anything of loudspeaker design and the efforts taken to quell structural resonances, you'd immediately suspect this structure of colouring the sound and – by carrying vibrations from one speaker to the another – of messing with the stereo image.
