Network Audio Players/Servers

It's costlier still than its predecessor, but Questyle's updated portable Digital Audio Player-and-dock combo delivers great sound quality – both at home and on the road

Shenzhen-based brand Questyle impressed the pundits with its debut QP1R digital audio player (DAP), launched back in 2015 at just the right time to exploit the increased interest in high-quality portable players and DACs. At first glance, the new QP2R looks very similar, with the same rugged and sturdy design – available in either gold or an Apple-esque 'space-grey' – and that distinctive armour-plated volume control protruding from the top of the device.

Making the step from software supplier to hardware brand, Roon has developed a pair of boxes designed to sit at the heart of a system. But what do they actually do?

Having been something of a ‘sleeper’ for a while, favoured by an admittedly growing group of computer-based audio enthusiasts, there’s every sign that Roon – the music server/database software – is finally going rather more mainstream. A number of manufacturers have launched products with, or updated existing models to, Roon-ready status, and now the company behind the software has entered the hardware market with a pair of hub components co-developed with Intel: the £1500 Nucleus, and the £2500 Nucleus+ we have for review here.

This flagship DAC from Canada, complete with a raft of in-house digital and power supply technologies, and very slick control app, is a complete network music solution

When is a DAC not a DAC? When it turns into a multifunctional network-connected music player, that's when! Increasingly, the lines between products that exist to convert digital inputs into analogue audio and full-blown network players are becoming blurred. So, just as there are players provided only with digital outputs – network transports or bridges to be paired with an outboard DAC – so we now have DACs with network capability built-in. Add an app running suitable UPnP control software, and you have a complete streaming solution.

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.

Having nailed the whole 'one box system with built-in speakers' category, T+A now shifts tack to a 'just add speakers' unit. It's on-trend, and with substance to match the style

Are we downsizing, simplifying, or just looking for more from less? Whatever the reasons, it seems the one-box system, to which one only needs add some speakers, is in the ascendant. There's no denying a movement is growing, with everything from 'more integrated' amps complete with onboard streaming through to complete systems such as the NAD M10/M33 [HFN Jun '19 & Aug '20], Naim's Uniti range [HFN Mar '11 & Nov '17] – which was in the vanguard of this trend back in 2009 – and the recently-announced Cambridge Audio Evo models [News, HFN Jun '21].

Packing a high quality DAC and streamer into a half-size box, this new digital converter also features powerful user-configurable DSP. It's a potent combination…

With this new DAC, for the first time in my design career, I have the chance to make an impression that has people saying “wow”', Daniel Weiss told HFN. 'Designed by our team here, it is different – but not radically so – to our earlier products.' He's being a little modest because the new Weiss DAC501 is more than a little diverting in any number of different ways…
