QXR Upgrade Card

Cyrus Audio are world leaders in audiophile high-resolution audio DAC technologies. Our amplifier, preamplifier and integrated amplifier products are all market-leading DACs capable of exceptional digital to analogue conversion. We have applied the principles of FPGA DASs, using the incredible speed and accuracy of the latest ESS DACs, combined with our advanced R&D experience in DACs to make the DAC filter slope incredibly shallow. Bu applying a shallow DAC filter slope, we are able to push the audible artefacts of phase discrepancy way beyond the audibility of the human ear.

We use advanced noise-shaping techniques to deliver exceptional DAC performance, which further lowers the noise-floor and provides exceptional sound quality and to develop the most substantial Cyrus DAC Upgrade ever.

Cyrus DACs are amongst the world’s best digital to analogue converters. We develop these DACs in our Cambridge headquarters, in the UK.

The Cyrus QXR DAC is available as a stand-alone product in the award-winning 82DAC and 6DAC integrated amplifiers products as well as the Pre2DAC preamplifier. This DAC is also available as an upgrade to integrated amplifier and preamplifier products from Cyrus which are up to ten years old.

The QXR card upgrade is the most significant improvement to Cyrus amplifiers in recent years. Bringing a world of the highest-resolution digital inputs to products up to a decade old through this High resolution Dac.

QXR works with numerous Cyrus products, not only improving the sonic performance through the addition of a 32bit/768k DAC and all-new asynchronous USB bridge but also substantially improving the performance of the headphone amplifier section of these integrated and pre-amplifiers.

To reserve your place in the upgrade queue, follow the buy link below. To find Cyrus retailer near you, please follow this link to our locations page.

The new QXR card is capable of processing PCM audio to 768k at a 32bit depth and ‘Native’ DSD 512, through the USB input. The high-specification ESS DAC uses asynchronous upsampling to deliver a sublime audio signal regardless of source. Even via the lower resolution digital S/PDIF and Toslink interfaces, incoming signals are ‘reclocked’ to substantially reduce noisy ‘jitter’ and deliver a refined, cleaner audio signal to the pre-amplifier stages of the upgraded product.

 

The improved headphone amplifier, included within the upgrade, reduces the noise floor, providing a much improved dynamic range. Capable of outputting 138mW per channel into 16ohm loads, it can comfortably drive headphones with impedances of up to 64ohm.

Gaming soundKey

Cyrus new soundKey USB DAC is revolutionising mobile music. It is compatible with iphone, iOS and android mobile and protable devices.

The majority of USB DACs and headphone amplifiers fitted to smartphones or laptops are the cheapest and most plentiful the manufacturer could find. And we all know what the results of that kind of policy are – just listen to the way your laptop neuters your favourite tunes when you plug your headphones into its socket.

At one end of the soundKey there’s a 3.5mm socket for plugging in headphones (or connecting to a system). At the other there’s a micro-USB socket. There’s no need (nor any room) for anything else.

In the box Cyrus soundKey USB DAC provides a cable terminated with a micro-USB at both ends (for use with appropriate Android devices) and a micro-USB/full-size USB cable (for use with laptop or desktop computers).

Those wishing to use an Apple phone or tablet will need the Apple camera kit, but using a dongle to attach an external USB DAC to a smartphone is far from uncommon, so it’s an acceptable compromomise.

The soundKey is ready to handle a wide range of digital audio file types, most pertinently MP3, AAC and FLAC – and can handle files up to 24-bit/96kHz resolution. It requires Windows 10, Android 5 (or above) and iOS 9 (or above) of its source machine.

Comparison with our current favourite at around this price, AudioQuest’s DragonFly Black, highlights the soundKey’s relative shortage of out-and-out dynamic heft – but at the same time, the Cyrus achieves the remarkable feat of making the Black sound like something of a blunt instrument. It’s significantly more revealing, more open and more detailed than the AudioQuest.

If we’re asked to make a trade-off between transparency and ultimate dynamism, we’ll come down on the side of the Cyrus every time.

Cyrus ONE HD

The Cyrus ONE HD is a High-resolution integrated amplifier ideal for use with your TV, Games console, laptop or desktop PC as well as many other audiophile sources.

The ONE HD builds upon the concept of the original Cyrus One, adding digital inputs including asynchronous USB, optical Toslink and coaxial digital inputs. All of these inputs are configured to work at high-resolution, up to 32bit, and are configured to get the very finest sound from whatever source you have.

The amplifier topology has been significantly updated beyond that of the original Cyrus ONE. Now in its fourth generation, our Hybrid Class-D design is now further refined with the signal path having been given a complete overhaul.

Cyrus design philosophy has been one of marginal gains. We have examined every performance critical component, upgrading wherever possible to improve the preamplifier stage, the power supply and the filtering. The result is an integrated amplifier with a host of digital inputs that is a sea change product in the development of the brand.

Bluetooth Enabled – aptX®HD:

aptX® HD compatible Bluetooth enables you to stream better than CD quality music from your phone/tablet or computer via a wireless Bluetooth connection, providing maximum flexibility without the need for a home network or any complicated setup. This allows everyone in the family to enjoy their music from their portable devices quickly and easily.

Digital and analogue inputs:

Asynchronous USB, optical and SPDIF inputs enable you to connect your PC, TV, Games Console, CD player, indeed virtually any source, directly to the Cyrus ONE HD. Four analogue inputs include RCA terminals for a turntable and an AV input that can be set to fixed gain in order to integrate with a separate AV amplifier.

Class AB Headphone Amplifier:

Uniquely, when headphones are connected, the large toroidal transformer is switched to power just the headphone section. These huge reserves of power result in a high power, high voltage class AB headphone amplifier that will drive almost all headphones with ease. The resulting musical performance is on a par with most standalone headphone amplifiers

Speaker Impedance Adjustment:

SID – Speaker Impedance Detection automatically matches the amplifier’s output response to the electrical load of the loudspeakers. This means that matching Cyrus ONE HD to any brand of loudspeaker has suddenly been made so much easier.

ONElinear

The Cyrus ONE linear is a premium loudspeaker system, which, whilst designed to perfectly augment the Cyrus ONE amplifier system, provides exemplary performance with a whole host of audio systems.

The ONE linear is engineered with a classically ‘British’ linear frequency response curve. The objective is complete neutrality, allowing the full character of the music to be revealed. A loudspeaker, however, can only be truly perfected if it is known which amplifier system will be driving it. In this case, the ONElinear has been optimised for use with our own hybrid Class D amplifier topologies.

The ONE linear bass/mid driver uses a double-wound copper-coated aluminium voice-coil. As well as being light, this produces a stronger induced magnetic field and hence ‘grip’ over hard to control bass frequencies. The voice coil is bonded to a carefully profiled KEVLAR cone material. This material is light and responsive, carrying limited inertia and retaining its shape and hence audio characteristic even when pushed hard. The speed and accuracy of the resulting bass response is remarkable for a speaker of the size.

The ‘tweeter’ or treble unit is a textile soft-dome, capable of meaningful response well beyond the limits of human hearing. Refined and balanced, the high-frequencies are never ‘aggressive’ or harsh, yet retain the full detail of the source recording.

The crossover uses high quality electrolytic capacitors to maintain the signal integrity and a smooth phase response through the transition from bass driver to tweeter. This again contributes the even response.

The cabinet has been developed using advanced computer modelling with ‘Delayed Cumulative Spectral Analysis’ to reduce the contribution of cabinet noise to levels more than 35dB below the driver output. The same computer modelling is also used to fine tune the crossover to ensure a consistent performance, even when listening ‘off-axis’.

The ONE linear is rear-ported and designed to be positioned between 10-30cm from a rear wall. This will optimise the bass response and mid-range clarity, although some experimentation with position is advised as this will be room-dependent.

PSX-R₂

External power supply – the Cyrus PSX-R2

The Cyrus PSX-R2 external power supply is a great addition to any existing Cyrus equipment that you may own. The PSX-R2 delivers an impressive increase in sound quality. It works by removing existing high voltage circuitry from inside the main Hi-Fi component isolating it from the sensitive, low voltage parts so important to music production.

The concept is that a power supply provides a super smooth DC feed to the highly refined electronics to you can hear the full potential of the products you have purchased.

In many products the PSX-R2 works in tandem with the built-in power supply to allow each part of the unit to be powered separately. It thereby removes any cross contamination from for example the motors in a Cyrus CD player.

The unit works by providing a regulated DC power feed free of negative artefacts that are present in all domestic mains supplies. Connecting a PSX-R2 external power supply enables the high grade components in the partnering component to perform to their full potential. This is one of our most popular upgrades and is highly recommended. The PSX-R2 provides new depth and detail to the sound output of partnering products by providing extremely low noise power to the circuits within the unit. Low noise high gain amplifiers connected in a propriety design filter out any unwanted noise and provide remarkable benefits in sound quality. If you consider that amplifiers and other audio electronics work by making copies of the incoming signal, it is obvious that the copy will sound better because if DC voltage lines are cleaner. A stable, strong and separated power supply can provide huge sound quality benefits for a hi-fi system.

By powering part of the workings of a Cyrus unit, the PSX-R2 lessens the strain on its internal power supply. This separation of power makes the unit work more efficiently, and creates a stronger and more detailed sound.

A fully regulated 300W DC power supply, the PSX-R2 uses intelligent connectivity which automatically adjusts its output parameters to suit the partnering Cyrus component.

The Cyrus PSX-R2 external power supply acts the same as most higher-end equipment. It has been long known that removing high voltage circuitry from the more sensitive low voltage parts will dramatically improve sound quality. Similarly providing multiple voltage supplies removes interference from one part of a device to another.

Cyrus has long produced the PSX-R power supply – an off-board power supply that isolates the high voltage components and allows you to enjoy your equipment at its best. They have however incorporated many enhancements to the AC and DC portions of this version of the power supply that they developed for the 30th Anniversary system. This enables the PSX to extract even greater levels of performance when partnered with recent Cyrus amplifier designs.

The Cyrus PSX-R2 power supply is compatible with most Cyrus equipment – you just plug in your kit into the PSX-R2 instead of the mains and enjoy!

The Cyrus PSX-R2 expernal power supply is highly recommended for the Cyrus CD players and transports that are often reviewed with this power supply as the incredible improvement decimates the competition!
