Veracity Audio launches Mystra – valve based dual mono, dual decoding PCM+DSD Digital to Analogue Converter (DAC)

For immediate release - Welton, Northamptonshire – Veracity Audio a British innovator in high-end audio, has launched its new offering: the Mystra digital to analogue converter.  Designed and hand built to order in the Heart of England, at launch Mystra DAC is available from; £3390 with a choice of custom levels and black or silver front panel finish.

Veracity says that the aim in designing this DAC is remarkable music reproduction.

Veracity Mystra product is a true dual mono design with dual DAC architecture. The dedicated 24bit dual mono conversion handles PCM format without sample rate change.  The stand-alone ΔΣ bitstream reconstruction filter plays back DSD64 and DSD128 natively, without digital processing. The Mystra is a dual DAC which auto-switches with the incoming signal file format: when the DSD is the incoming format it will go to the DSD reconstruction filter.  When PCM is the incoming format it will go to the parallel PCM only DAC. Through direct connection, both engines share only the valve analogue stage, on a 'one-at-a-time' basis.

The Mystra DAC is fully featured for any two channel digital audio application: 2 x RCA COAX (optional AES/EBU, BNC) digital inputs, multi-format asynchronous USB input, analogue preamplifier function and stereo RCA and XLR outputs.

To precisely match the output of the DAC to any pre or integrated amplifier, Mystra DAC is equipped with analogue volume control. The non-inductive audio resistors are switched by relays in R2R shunt operation mode, meaning that only two resistors are in the signal path at any volume level. This discrete, stepped attenuator has 87 levels. For purist, minimalistic systems, this volume control will facilitate direct connection to power amplifiers. Volume control and input selector operation is remotely controlled with a custom, handmade handset.

With a total focus on SPDIF signal quality and unique to the design, a new quad differential receiver with jitter rejection was developed. This works with any CD transport and other compatible sources.

The DAC is equipped with a line preamplifier option. An external analogue source can then be linked directly to the DAC valve stage, the latter becomes an active preamplifier with R2R volume control. Analogue input is a pair of RCAs. Output is via main analogue outputs, RCA and XLR.

Mystra DAC features an output for 32Ω - 300 moving coil headphones. A minimalistic high current design, solid state driver, takes the signal directly from the valve output and is capable of up to 250mA signal current delivery.

The valve analogue output stage operates in pure Class A.

It is a single ended triode design without negative feedback and has original Veracity topology. It remains true to the source phase of the signal.

The valve signal amplifier features bias reference generator and active triode loading. Here one valve triode works as a current source to another valve triode for pure, symbiotic operation.

The DAC features low impedance, high current drive audio outputs. Jensen Copper foil audio capacitors are used for signal. Both single ended RCA and XLR audio outputs are coherent with any amplifier with RCA`s 209 and XLR`s 600output impedance.

The valve stage consists of a pair of 6SN7 signal drivers, a pair of ECC82 output drivers and a pair of CV574 full-wave valve rectifiers. To personalize the sound, Mystra DAC includes ‘valve rolling’ flexibility, so users may match their tonal preferences. Information about valve replacements are published on the Veracity website in their Why+FAQ section.

To keep the signal path pure and simple, non-saturating, jitter free- analogue relay switches are used for all signals. Cmos, mux transistor signal switching is not used.

Veracity Audio believes that power supplies are the most important element of audio design. With the Mystra DAC, they have not only separated the digital and analogue power supplies but also the left and right channels. This was done from ground-up including the 3 independent mains transformers chosen from Talema. Discrete Schottky rectifiers supply power to strictly linear, ultra-low noise voltage regulators. Analogue stage is powered directly from full wave, twin valve rectifiers. Each power recipient has its own power supply, including the internal linear power supply for the USB interface. These 20 power supplies are fast and capable of high current delivery featuring separate power rails with dedicated decoupling for each power load. A system of multiple choke filters, ultra low impedance film and organic polymer capacitors is used, to provide the purest power flow possible. The DAC also features a built-in, CLC mains filter selected from Schurter.

Mystra DAC is equipped with ‘soft start’ (turn ON delay), giving the time for the valves to warm-up. During this warm-up time signal outputs are muted. The sound comes on automatically after 70 seconds from powering up.

The unique Veracity casework is three Faraday cages joined together into a monocoque structure. This provides the circuitry with an extremely high-stability mechanical base, EMI & RFI screening and resistance to vibration. The casework is polymer coated. The internal aluminium/viscoelastic rubber lining, additionally protects against vibration. The aluminium top cover and removable valve cover are the only structural parts fitted with screws. The DAC is also directly fully grounded via the safety earth pin in the fused IEC socket. Direct grounding gives the highest electrical safety and a direct escape route for EMI/RFI interference.

95% of parts are sourced in the UK and the DAC is totally hand-built in England. Veracity uses the latest analogue and digital components and thoroughly modern engineering. Every component is selected purely for its sonic characteristics and reliability. Each unit is soak-tested for 24 hours prior to shipping. Veracity is confident with the reliability of its products and issues a three-year guarantee from delivery date.
