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.
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.
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.
Compatible File Formats and Resolutions: PCM audio to 768k at a 32bit depth and DSD native 512.
Moving to a separate pre-amplifier and power amplifier offers another level of refinement to enthusiasts looking to upgrade from an integrated amplifier, or those looking to build a reference-grade system. A two-box set up enables the pre and power amplifiers to be run by separate power supplies resulting in a cleaner signal as the inductive effects of the large currents in the power amplifier are isolated from the sensitive components of the pre-amplifier.
The effect is astonishing. The experience is cleaner, more powerful and fantastically engaging. You will rediscover your collection with a whole new perspective on the performance. The Pre2 DAC is our first step on the pre-amplifier ladder.
The Pre2 DAC separates the pre amp into its own chassis and provides a dedicated power supply which means the pre amp can resolve more detail. Complete with a built-in DAC, the pre amp is compatible with a very wide range of sources such as CD players, streamers or your TV digital audio out.
The Pre2 DAC offers a sonic step up in performance from our integrated amplifiers. This is achieved because the pre amplifier circuitry has its own power supply. The internal power supply provides isolation from the demands of other system elements, making available an additional level of dynamics and resolution. The digital section also sounds better for the same reasons, especially when used with the optional QXR card, the audio quality rises further still.
If a PSX R2 is connected, owners will hear a large jump in performance as the PSX R2 feeds the pre amp with a highly regulated and super smooth DC feed. The sonic uplift from the PSX R2 means the close tolerance components in the pre amp can be fully appreciated as they now benefit from the smoother supply.
The Pre2 DAC includes a carefully designed top quality digital section built into the pre amplifier with a Burr Brown 24-bit/192k DAC and a carefully designed power supply (Pre2 DAC only). With 5 digital inputs that enable the amplifier to connect and clearly improve the sound of connected digital sources including; your computer, DVD player, TV and many other digital sources. Our premium QXR DAC upgrade is available which takes performance to a higher level again.
The Pre2 DAC is designed to be partnered with one of our matching power amplifiers such as the X Power, Stereo 200 or Mono X 300 Signature. Build your system with a CD i or CD t and a Stream X Signature or Stream Xa for an exceptional music experience. Add a dedicated power supply such as the PSX R2to further enhance the pre amp’s resolution.
