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'.

As one approaches gear at lower price points, every pound matters that much more. It's simply a fact of life: the customer for Auris Audio's Nirvana high-end headphone amp [HFN Jun '19], at £4900, might be cavalier about issues such as value-for-money, features, finish or other details. Not so the prospective client for Auris Audio's £1499 Euterpe, because the market is over-burdened with serious competitors and money is more of a determinant.

Considering where Pro-Ject's Box Design range started, it's come a very long way. It all began with a compact and very affordable phono stage, the original Phono Box, launched as an interface between the company's wildly successful lineup of turntables – which arguably spearheaded the entire 'vinyl revival' – and the amplifiers of the time, many of which had long since dispensed with inbuilt phono equalisation.

Agood hi-fi system should invoke 'passion' in the listener – be that an urge to crank-up the volume, to play an air guitar or wave an imaginary baton. French brand YBA knows this only too well, bestowing this particular moniker on its penultimate lineup of models. Coming in below its Statement units, but above Design, Heritage and Genesis, the six-strong Passion range also includes the PRE550/AMP650 pre/power amplifiers [HFN May '18].
