Surprises, at my age, could prove fatal, so I neither invite nor encourage them. Even pleasant ones. Neither do I relish my preconceptions being challenged: 'Old dogs, new tricks...' That said, and despite spending countless hours listening to assorted Constellation systems over the years, I must admit to being unexpectedly bowled over by these Inspiration Mono 1.0 power amplifiers.

Something is afoot in the land of hi-fi separates. First we had Musical Fidelity with its M2scd/M2si [HFN Jul '19], then Cambridge Audio's AXC35/AXA35 [HFN Sep '19] and now Rotel has launched its own affordable amplifier and CD player pairing, in the form of the £429 CD11 and £599 A11.

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.

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'.
