Cyrus QXR DAC Upgrade is the most drastic improvement to Cyrus amplifiers in recent years updating products that are up to a decade old by bringing a host of highest-resolution digital inputs.
Cyrus QXR functions with many Cyrus products, not only enhancing the audio performance through the addition of a 32bit/768k DAC and all-new asynchronous USB bridge but also significantly boosting the performance of the headphone amplifier section of these integrated and pre-amplifiers.
QXR is capable of handling PCM audio to 768k at a 32bit depth and ‘Native’ DSD 512, via the USB input. The high-spec ESS DAC incorporates asynchronous upsampling to produce a sublime audio signal no matter what the source. Even signal received from the lower resolution digital S/PDIF and Toslink interfaces are ‘reclocked’ to drastically lower noisy ‘jitter’ for a refined, clearer audio signal to the pre-amp stages of the component.
The upgraded headphone amplifier, featured within the upgrade, lowers the noise floor delivering a substantially augmented dynamic range. It is capable of outputting 138mW per channel into 16ohm loads so it can comfortably drive headphones with impedances of up to 64ohm.
This update makes the amp so much more versatile by adding superb sounding digital options. HiRes from the MAC sound amazing.
