Description
The DAC X+ is a very high performance Digital to Analogue converter. Partnered with a CD Xt SE+, it provides Cyrus' ultimate CD player.
The DAC X+ is all about accuracy. First a highly accurate reference clock is used to lock together a special Sample Rate Converter and the Digital to Analogue Converter for maximum digital accuracy. After re-clocking the input signal is up sampled to 192kHz before being fed to twin stereo DACs designed in dual mono configuration for balanced operation. The other operational elements of the system are optically isolated from the twin mono DACs improving clarity.
The DAC X+ has customisable inputs, with each input capable of being re-named from a wide list of options allowing fit any system. The input names are displayed on a clear soft green backlit LCD display matching all other Cyrus components.
The DAC X+ will slave “on”, through the Master Control BUS with any Cyrus CD player.
The overall result is an easy to use, compact, exceptionally high quality DAC, which is able to elevate the performance of many different sources, to top audiophile levels.

More Details
D/A conversion – At the heart of a quality D/A converter is the circuit that converts the digital source signals to analogue. Careful design of this circuit is essential to retrieve the true dynamics of the source signal and to minimise undesirable artefacts such as noise and distortion. The DAC X achieves this with a two stage upsampling design where all sources are initially upsampled to 192k before analogue conversion by quad high-precision 24-bit converters operating in a fully balanced configuration. The technical specifications endorse the quality of this stage with class-leading performance for THD and noise. The elevated 192k sample rate permits our designers to use far less aggressive analogue filtering techniques to remove undesirable out-of-band digital noise.
Jitter reduction - All audiophiles understand that low jitter is an essential requirement for the clocks and data signals passed within a D/A converter. In the DAC X+ the sophisticated re-clocking circuit measures the precision of incoming digital signals to determine the quality of the input source. High accuracy sources such as the CDXt SE+ CD transport are digitally re-clocked by a close tolerance circuit with triple quartz references. For signals from low accuracy sources such as personal computers the circuit automatically relaxes the re-clocking precision to ensure reliable signal recovery.
Sample rate handling – The DAC X+ is prepared for the wide range of sample rates available from today’s digital sources and beyond. Group 1 close tolerance performance is available for 32k, 44.1 k, 48k, 64k, 88.2k, 96k, 128k, 176.4k, 192k source material. For sources outside of Group 1 requirements, any sample rate in the range 32k – 192k is accepted. Non-stereo waveforms (surround sound etc) are identified and suppressed to avoid undesirable digital noise.
Digital output – An optical digital output provides a useful digital feed to send the signal from the selected source to digital recording devices or to a multi-channel surround sound decoder.
Power supplies –The DAC X+ power supply is a traditionally built linear design, with an oversize toroidal power transformer including twin windings dedicated to the digital and analogue sections and entirely separate power regulation for the DAC and analogue filter sections. Two-stage regulation is used for critical stages with remote shunt regulators located within the heart of the audio circuitry. A custom designed ultra low noise torroidal power transformer ensures that each section of the DAC X+ receives an unrestricted, noise free, power supply.
DAC XP upgrade – By returning the DAC X+ to the factory, a complete high-end pre-amplifier stage with separate power supply can be added, bringing the DAC X+ up to full DAC XP+ specification.
