The Nu-Vista DAC is our new flagship DAC built around the critically acclaimed ESS 32-bit HyperStream II DAC architecture. The Nu-Vista DAC incorporates our famous Nuvistor circuitry, each channel having a fully balanced stage of Nuvistor 7586 triode tubes involved in a discrete Class A amplifier buffer. It features RCA and XLR outputs, 3x optical and 1x coax SPDIF inputs, 1x USB and 1x AES/EBU inputs. A I2S input is also there, for a future yet to be announced Nu-Vista CD-player!
 
Technical Talk
Building on our knowledge and experience with Sabre ESS chips, the Nu-Vista DAC uses 2x ES9038Q2M chips in dual differential mode for a pristine dual mono design. Thanks to these converters, the Nu-Vista DAC supports up to 768 kHz files in PCM and DSD256 via DoP and native DSD512 via USB, covering any digital file you can buy or stream. The SPDIF inputs are greatly improved as well, now supporting MQA (up to 384kHz) and DSD (DoP 64) as well!

Digital Architecture
We utilize an extremely low-noise, low-dropout regulator designed specifically for high-performance audio systems and optimized for high-resolution audio thanks to its revolutionary dual-regulator architecture. The inclusion of a Time Domain Jitter Eliminator results in superb SNR and THD+N performance with unbelievably detailed transient response. Digital audio is the art of time, with our proprietary clock design we have managed jitter rates of unrivalled and below 100 femtoseconds. This outperforms many renowned and respected audiophile clock generators! Other advances in the DAC section include optional upsampling and reclocking and an oversampling bypass mode. The 16-core XMOS and CPLD MAX II Altera processors ensure there is always enough headroom for these operations, the digital filters, including our own new proprietary filter for optimum transient response, and the MQA processing.
