Vivaldi CD/SACD Transport

Vivaldi Transport is designed to extract revelatory levels of detail from both CD and SACD and is the ultimate machine for silver disc replay. All signal processing in Vivaldi Transport is controlled by electronics designed by dCS. It uses the TEAC Esoteric VRDS Neo™ mechanism which provides a brushless motor with heavy flywheel for stable disc rotation and super rigid construction.

The powerful digital processing platform of Vivaldi Transport is based around Field Programmable Gate Array (FPGA) chips, Digital Signal Processing (DSP) chips and a microcontroller system. All of these use code developed and maintained in-house by dCS.

Vivaldi Transport represents true state-of-the-art in digital audio by offering twice the logic capacity of previous generations, delivering unmatched sonic and measured performance.

In order to enhance the cleanness of the power supply and isolate the mechanism from the electronics Vivaldi Transport features a completely new chassis design that has separate power circuits for the digital processing and CD/SACD mechanism sections. This has resulted in near silent operation.

Vivaldi Transport features a Dual AES output that supports dCS-encrypted DSD (1 bit data at 2.822MS/s) to a dCS DAC from SACD.  Vivaldi Transport also offers the option of upsampling CD data to DXD (24 bit data at 352.8kS/s) and transmitting this data over the same Dual AES interface.

SACDs are played in their native DSD format, again using the Dual AES interface. Native CD data is available from 4 PCM outputs (1x AES/EBU and 2x SPDIF, 1x SDIF-2), as is down-sampled SACD data.

Vivaldi Transport is intended to be used with the matching Vivaldi DAC or with any suitable industry standard DAC. The unit may be run either in Master mode or with the DAC as the system clock. Performance will be enhanced further by adding Vivaldi Clock to the system.  

The dCS ‘soft’ approach to programmable logic makes it extremely easy for users to update Vivaldi Transport software, whether adding new features, installing performance upgrades or adapting to changes in digital formats.

Vivaldi Master Clock

The dCS Vivaldi range redefines state of the art in digital playback representing the pinnacle of our ‘no compromise' approach to product design and setting a new standard for the future of digital audio by delivering an unrivalled in-home musical experience. Vivaldi Master Clock is a powerful yet simple to use Grade 1 master clock based on our pioneering developments in studio and home audio. Featuring two banks of clock outputs capable of outputting different frequencies, Vivaldi Master Clock uses the latest groundbreaking technology from dCS. In a digital audio system samples must be accurate in level and time. Jitter, which exists in all digital systems, can result in timing errors in these samples causing the analogue signal to be reconstructed inaccurately. In a dCS system our DACs can act as the system master clock, but listening tests have shown that there is no substitute for a high-quality, dedicated master clock. dCS were pioneers in the use of external clocks in digital audio systems and our clocking technology has been continually refined so that our latest multi-stage Phase-Locked-Loop (PLL) system sets world-beating standards for accuracy and control of troublesome jitter from the incoming audio stream. All dCS Master Clocks are subjected to rigorous in-house testing. The crystal oscillators are pre-aged, selected for long term stability and then individually calibrated over a wide temperature range to ensure consistent optimal performance. Vivaldi Master Clock uses a sophisticated microcontroller system to ensure smooth correction as the temperature changes and this approach gives a more stable result than either oven controlled crystal oscillators or even atomic clocks. All dCS master clocks are designed to generate industry standard Word Clock on 75 ohm co-axial cable. Other manufacturers' equipment that has been designed to accept standard Word Clock can be used with our clocks. Vivaldi Master Clock may be slaved to an external reference (such as an atomic clock or GPS reference) if increased accuracy is desired. Our sophisticated multi-mode Phase-Locked-Loop (PLL) significantly reduces jitter from the reference source. The dCS ‘soft' approach to programmable logic allows the user to easily update Vivaldi Master Clock software, whether this is to add new features, improve performance or adapt to changes in digital formats. Used as part of the Vivaldi digital audio playback system Vivaldi Master Clock improves on an already spectacular sound and takes it into an entirely new domain. With a clock added to a dCS system images snap into sharper focus and the music displays a substantially greater sense of authority and power as well as, most importantly, offering noticeably higher resolution of detail.
