Network Audio Players/Servers

The Norwegian brand’s latest amp is not just its most powerful integrated, but comes complete with network audio capability. Is this the ultimate one-box amp solution?

Obviously not afraid of a spot of (Russell?) crowing, Oslo-based Hegel describes its new Reference H590 integrated amp, just going on sale at £9000, as ‘Master and Commander’. Apparently it’s ‘A master at musicality’ and ‘The commander of any set of speakers’. Mind you, you might be tempted to forgive the company for its exuberance – after all, the new arrival is something of a monster, standing an AV-receiver-challenging 17.1cm tall, tipping the scales at 22kg and delivering over 300W per channel. Well, 301W a side actually, according to Hegel, making it at least 50% more powerful than its previous top integrated, the H360.

Here’s a network audio bridge, a USB player and computer audio cleaning device, and a Roon Ready endpoint – all in one tiny (and affordable) box. Is there anything it can’t do?

The rise of ‘computer audio’ has rewritten the rules on hi-fi components. What once required a full-width separate can now be achieved with an almost vanishingly small box of computer technology, all ready to connect into your existing system. You can stream using a Raspberry Pi, an Asus Tinkerbox or an Intel NUC – to name but a few – and a whole industry has sprung up making add-ons for these mini-computers to turn them into digital or analogue audio devices, or even complete ‘just add speakers’ systems.

The company ups the ante by adding a 'just-add-speakers' solution to its Artera series, managing to squeeze streaming alongside CD replay into casework of pert proportions

So far, Quad's Artera family has comprised the Play (a combined CD transport, DAC and preamp) and the Stereo [HFN Nov '15], which is a power amp using the company's Current Dumping topology. Both solid-state components, not only are they compact and dapper but high functioning and lifestyle literate too – a feat that's trickier than it might seem. But not as tricky as folding all of the above (plus streaming) into a chassis with the same proportions as the other components in the Artera range.

Hugely flexible, hugely capable and, well, just plain ‘huge’, dCS’s flagship Vivaldi four-box digital stack has been condensed into a one-box solution. So why a limited edition?

There comes a time when you have to pop the champagne cork, relax and have fun. That’s what dCS (Data Conversion Systems Ltd) has done with its new £55k Vivaldi One single-box disc player/upsampling DAC/streamer. It’s a limited edition of just 250 pieces, designed to celebrate the company’s 30th anniversary. In that time, the company has gone from being an Official Secrets Act signatory supplying advanced radar systems for the RAF towards the end of the Cold War, to one of the most respected high-end digital audio specialists around.

Lindemann audiotechnik, a boutique brand from Germany, has focused on high-end music replay for the past 20 years. It was one of the world’s first high-end brands to offer an outboard USB-to-S/PDIF converter for connecting a computer to a DAC. And it was also quick off the mark to make a USB-equipped DAC. Identifying a new trend for ‘downsizing’ complicated audio rigs, it has developed a range of four midi-sized – if expensive – products dubbed Musicbook.

Sony has returned to pure, two-channel, high fidelity sound; there’s an initiative to bring hi-fi replay back to the top of its consumers’ must-have wish lists. And it has produced a raft of new products focused around hi-res computer audio. All are compatible with files up to 24-bit/192kHz and, of course, DSD downloads. HFN was first in line to sample the ‘Elevated Standard’ HAP-Z1ES digital music file player featuring a built-in 1TB HDD, and its partnering TA-A1ES integrated amplifier rated at 80W/8ohm.

Krell announced at the 2014 Las Vegas CES its intention to introduce a UPnP/DLNA-compliant network media player and the rather aptly named Connect is now available in the UK. There are in fact two versions of Krell’s Connect player, the one featured here having an optional built-in DAC with balanced (XLR) and single-ended (RCA) analogue outputs. Needless to say it is vastly overbuilt compared with most music streamers! At its core lies a familiar BridgeCo-based StreamUnlimited platform including vTuner internet radio functionality. Massive power supplies have always been the cornerstone of Krell designs, and the Connect has an over-specified linear power supply with a 94VA toroidal transformer large enough to power a modest amplifier.
