Due on sale in the UK mid-March is the NAD Masters Series M51 DAC (digital-to-analogue converter) for £1500.
NAD is claiming a number of 'firsts' for this flagship model, including HDMI support, USB Class 2 audio with 192kHz capability, digital error correction and 35-bit architecture.
A Pure Class A analogue stage with low output impedance provides "the perfect interface to your amplifier", says NAD. Both balanced and single-ended outputs are available.
The M51 is also a fully functional digital preamp with seven digital inputs and its own volume control.
As well as having standard AES/EBU, optical and coaxial inputs, the M51 also includes the latest USB technology supporting 192kHz, rather than the usual 96kHz.
More after the break
With both host and device USB ports, users can connect a Mac or PC in addition to a USB flash drive or hard disc.
You also get two HDMI inputs and one HDMI output with video pass-through so the M51 can be used as part of a 2.0 video system using the two-channel linear PCM soundtrack on any Blu-ray or DVD.
