Yes, they’re expensive – but Nagra’s electronic jewels are gloriously timeless and beautifully engineered. The new Jazz preamplifier maintains the compact form factor and familiar brushed aluminium casework synonymous with the marque – it’s a Nagra through-and-through. And Nagra says the preamp’s circuitry – which employs 2x12AX7/ECC83s and 1x12AT7/ECC81 dual-triode valves – has been completely rethought to improve stability and reduce noise to the point where its engineers no longer consider a battery power supply a necessity. The Jazz is powered by a hideaway PSU that delivers DC to the main unit via a cable terminated with a Lemo connector.

This is Chord’s first network player. What it has done, in effect, is to marry its top-of-the-range QBD76 HDSD DAC with StreamUnlimited’s Stream700 audio streaming client – an off-the-shelf hardware solution for network audio which includes a 3. 5in, 320x240 pixel colour display, supports up to 24-bit/192kHz FLAC or WAV files via wired Ethernet (24-bit/96kHz via a wireless connection), provides for internet radio and offers remote control via a smartphone app. There are just two rear inputs –a BNC socket for S/PDIF connection and, of course, the Ethernet socket – and just two pairs of phono and XLR outputs: one at fixed level and one a variable output, adjusted by an analogue volume control within the DSX1000, which allows for direct connection to a power amp.

Since reviewing T+A’s DAC 8 converter [HFN Oct ’12] it has become something of a reference for us. The same DAC architecture has been transplanted into this luxuriously built multi-function media player, the first of a new line of high-end pure audio components, dubbed ‘HV’ for High Voltage [see also p73]. The MP 3000 HV comprises a CD player, a UPnP network client for computer-sourced music streaming via Ethernet or WLAN, an internet radio incorporating thefamiliar vTuner platform, and an FM radio tuner with RDS. Naturally, since it has a high-end DAC at its core, it features an asynchronous USB input for ‘pushing-in’ audio data from computers, and it sports no fewer than six digital inputs at the rear to accommodate a plethora of digital sources as well.

If proof were needed of Bryston’s mettle for embracing the modern world beyond purist two-channel analogue pursuits, it’s the B135 SST2 C-Series Integrated Amplifier. While the unit reviewed here is two-channel, purist and analogue, it can be fitted with a DAC module for £1575 that adds two coaxial and two Toslink inputs. Other options include a £500 universal remote and an MM-only phono stage for £650. Bryston offers neither MC nor USB.
