LATEST ADDITIONS

These are just the first two models in Roksan’s new Oxygene series. In the amplifier, the use of Class Dor switching-amplifier technology provides high power and excellent performance from a physically compact package. There’s very little heat dissipation, so the amplifier doesn’t require big heatsinks or a lot of ventilation. The designers have chosen one of the well-known range of Hypex UcD modules, which have a high reputation for sound quality.

At the heart of Simaudio’s 380D DAC/preamp is its M-AJiC32 processing (Moon Asynchronous Jitter Control in 32-bit mode) and at the core of this is an eight-channel ES9016S Sabre DAC from ESS. Simaudio claims to have further improved jitter performance with its own ‘Alpha Clocking System’. The 380D has separate power supplies, each with a toroidal transformer and 11 stages of voltage regulation, for its digital and analogue sections. The analogue stage is a fully differential circuit and balanced XLR connections are strongly recommended, although RCAs are also provided.

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.
