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.

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.

The bi-wire output of the 82 DAC gives a full 88 Watts into 6 ohms – enough to drive even the most demanding loudspeaker loads. To ensure the highest standards of quality, the power supply is a high current design that uses two transformers to completely separate the digital control stages from the sensitive audio signals – an approach usually reserved for pre/power combination amplifiers.
