dCS Vivaldi Apex DAC
The digital core of the Vivaldi system, our renowned DAC decodes audio with remarkable precision. Equipped with the latest generation dCS Ring DAC™ APEX, it offers unparalleled performance characterized by exceptional realism, depth, and emotional engagement.
KEY FEATURES
- dCS Ring DAC APEX™ hardware further reduces distortion and improves linearity for enhanced musical performance
- Utilizes the latest generation dCS Digital Processing Platform for state-of-the-art measured performance and unrivaled fidelity
- Designed for maximum flexibility by accepting audio data from a variety of digital sources
- Flexible output configuration can be optimized in systems with or without preamplifiers
- Comprehensive clocking architecture plus an auto-clocking mode used in the Vivaldi range improves ease of use and minimizes jitter
- USB interface allows easy connection to a computer, accepting PCM data at up to 24/384 and DoP (DSD/64 or DSD/128 over PCM)
- The interface runs in asynchronous USB mode, making the DAC immune to jitter from noisy computer master clocks
- Improved power supplies give lower running temperature and superior tolerance to AC supply variations
- Multi-stage regulation ensures sensitive analogue circuitry is unaffected by digital interference
- Separate power circuits for the digital and analogue sections further enhance the purity of the power supply
- Aerospace-grade machined aluminium chassis fitted with tuned acoustic damping panels reduces magnetic effects and vibration
- Features a full MQA™ decoder. This MQA™ implementation is unique, as it is the first opportunity to enable a DAC which, by providing exact rendering to beyond 16x (768 kHz), matches the desired temporal response with very low modulation noise
