Detailed mechanical and component upgrades to B&W's flagship 801 D4 unmask the speaker's full potential
We've been here before: just over a year and a half ago [HFN Nov '21] we pitched the newly arrived 801 D4 loudspeaker from Bowers & Wilkins against the 800 D3, its previous flagship, and played 'spot the differences' between two designs half a dozen years apart. At the time, we also commented on the changes at the company since the D3 models were launched in 2015, not least the acquisition of the Worthing-based manufacturer by Silicon Valley start-up Eva Automation, then by Sound United, the parent brand of Denon, Marantz and others.
Celebrating a legacy that stretches back 50 years, the Norwegian brand stamps its authority with the heavyweight AW 800 M flagship amplifier – a solid cube of power!
There's a classical simplicity about this flagship pre/power amplifier combination from Electrocompaniet. The style – realised here with clear-on-black acrylic fascias with gold detailing – harks back to its first amp, 'The 2 Channel Audio Amplifier' [HFN Dec '11], based on Dr Matti Otala's tackling of 'Transient Intermodulation (TIM)' distortion, shortly after it began operations in 1973.
The premier 'server/player/reclocker' from New Zealand brand Antipodes Audio boasts a host of proprietary technology and supports up to 24TB of user-installed SSD storage
Network audio is a significant growth area in hi-fi, helped along by network-connected transports and servers, designed to be used into offboard DACs. We used to call these devices 'network bridges', interposed between the home network, and any storage devices thereon, and an audio system. Nowadays they've grown beyond that basic functionality, being able to access music stored internally or via directly connected drives. Meanwhile, the 'network connectivity' is used to access online streaming services, and offer remote control via a tablet or smartphone app.
With an impressive back-story, impeccable engineering and glorious finishes, these imposing '5th generation' Italian speakers promise much – so do they deliver? Certo!
The Amati G5 sits at the top of a four-strong new 'fifth generation' range of the company's Homage speakers, so-called because they pay tribute to the tradition of musical instrument manufacturing in Cremona, Italy. And they do so not just in name, but in the way they're made, with extensive use of selected woods, handcrafting based on the work of traditional luthiers of the past, and even a lute-shaped profile, which first saw the light of day in the previous Homage series [HFN Oct '17].
The high-value Edwards Audio range from Talk Electronics now includes no fewer than four integrated amps, the IA1 also equipped with motorised volume and remote control
While there is a drive to bring (hi-fi) manufacturing back home to Blighty, some brands never left. One such stalwart is Edwards Audio, a sub-brand of the longstanding Talk Electronics range of full-width components. The Edwards Audio IA1 integrated amplifier on these pages is handmade in the UK – yes, designed, engineered and assembled here – and yet costs just £430. Still not convinced? Well, you can have a simpler version of the same amp, shorn of remote control, for £60 less, and you can even buy both versions in red, white or blue – but not all three at once – as part of a range of six acrylic colours in which Edwards Audio offers its full stable of products.
Aurender's flagship two-box network music library isn't the traditional PSU/player you might expect. Instead, the functionality is elegantly split between data in and data out
Look at any multi-box component and you can usually work out what's going on: CD transport and DAC, preamp and power amp(s), for example. But just as often those two boxes are an 'audio product' – phono preamp, headphone amp, DAC or even a digital audio transport – plus an outboard power supply. The rationale for these latter two-boxers is clear, for by isolating the electrically noisy parts of the system away from delicate audio signals, interference is minimised and signal purity maximised.
The 'Blade' models fly the flag for KEF's speaker tech, but its Reference 5 offers a more accessible route to 'high-end Uni-Q'
Fortunately, the Reference 5 Meta is the £17,500 flagship of KEF's 'conventional' speaker range, bettered only by the striking-looking Blade designs [HFN May '22]. Fortunately? Well, yes, because this is an imposingly huge design, standing just over 1.4m tall, even if some of that impression of scale is minimised by the slenderness of the cabinets. Indeed, if the enclosures were any narrower than their 205mm, there wouldn't be room on the front baffle for the quartet of 165mm aluminium-coned bass drivers, arranged in pairs above and below the company's 12th-generation Uni-Q treble/midrange unit.
They started out as a Concept, and have become a reality combining a skeletal form and novel engineering solutions – but do they sound as other-worldly as they look?
As safe bets go, that you've never seen anything quite like the £70k Monitor Audio Hyphn speaker is pretty much a dead cert. Yet look closer and there's actually a lot of 'form following function' going on here in those two columns with a gap between them, linked by a central belt. And while to unsympathetic eyes they may look like two huge clothes pegs, it won't take long for audiophiles to understand the thinking behind the configuration, however unusual the speakers look by comparison with traditional 'box, domes and cones' designs.
Based on the Tesla G2 platform used in Auralic's premier G2.1 range, but lacking the box-in-box build and some circuit detailing, the Aries G1.1 remains a top-flight streamer
Yes, the £2699 Aries G1.1 is another one of those similar-looking Auralic components that will blend seamlessly with its brand partners, even if we're never immediately sure what box does what... In this case, we have a network player without onboard digital-to-analogue conversion, designed to be used straight into an external DAC. In this guise, it brings the niceties of Auralic's Lightning Streaming Platform, and its Lightning DS control app, to owners of third-party DACs. This also includes amps or preamps with digital inputs, which can be fed via USB or optical, coax or AES.
From Germany's SPL (Sound Performance Laboratory) comes this multicolour USB DAC designed for both 'legacy' and computer connection. There's a volume control too...
Given that most of today's digital components seem to be multifunctional – streamer DACs, DAC/headphone amps and the like – it's unusual to find a product as simple in its operation as its design. Yet that describes the latest arrival from German manufacturer SPL, the £2499 Diamond DAC, available in silver, black or red like all the company's products. A back-to-basics DAC? Well, almost...
