Vivaldi DAC features standard AES3, Dual AES, SDIF-2 and S/PDIF inputs in addition to an asynchronous USB 2.0 interface. The enhanced digital volume control allows direct connection to a power amplifier so that in the majority of systems there is no need for a separate preamplifier. Maximum output can be set any one of four levels to suit different amplifier and speaker combinations.
APEX is a new, enhanced version of the dCS Ring DAC™: the Digital to Analogue conversion system found inside all dCS DACs. First developed for our professional audio products, this unique system has been subject to continuous development and refinement over the past three decades, and remains renowned for its technical and sonic performance.
With APEX, we’ve reconfigured the Ring DAC’s™ circuit board and developed a new analogue output stage. This has allowed us to further reduce distortion, and increase linearity, resulting in a range of measured and sonic improvements – including an even greater sense of dynamic drive, detail, finesse and vitality.
The powerful digital processing platform of Vivaldi DAC is based around Field Programmable Gate Array (FPGA) chips, Digital Signal Processing (DSP) chips and a microcontroller system. All use code developed and maintained in the UK by dCS. Offering twice the logic capacity of previous generations, Vivaldi DAC is the current state-of-the-art in digital audio, delivering unmatched sonic and measured performance.
dCS pioneered the use of external clocks in digital audio systems, and the redesigned multi-stage Phase-Locked-Loop (PLL) system used in Vivaldi DAC sets world-beating standards for accuracy and control of troublesome jitter from the incoming audio stream.
Featuring a completely new interface designed to handle all high resolution musical formats up to DXD (24-bit data at 352.8 and 384kS/s) plus DSD/64 or DSD/128, the optimised DSP filters available to Vivaldi DAC owners will ensure you can extract every last nuance of musical detail and emotion by tuning the system to suit your personal preference.
