    Cyrus announces QXR DAC upgrade card
    Cyrus Audio today announces the launch of a significant upgrade card available for its classic amplifier range.
    The QXR is a digital interface card that features a significantly upgraded DAC (digital to analogue converter) and all-new asynchronous USB bridge capable of handling up to 32bit 768k and DSD512 high-resolution audio files. As well as this uplift in sonic capability, the performance of the built-in headphone amplifier has been improved.

    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 quality 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 cleaner audio signal to the pre-amplifier stages of the host 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.

    Available in the following products from Cyrus, the 6 DAC QXR, 82DAC QXR and Pre2DAC QXR, the new DAC is also available as upgrade card that can be fitted to any of the companies preamplifiers from the last decade. Cyrus have previously supported their products through offering upgrades and it allows systems to improve in both longevity and quality.

    Simon Freethy, managing director, says, “This upgrade offers customers with amplifiers up to nearly a decade old, the ability to bring their systems right up to date. Capable of handling even the highest-resolution files, the performance uplift is nothing short of remarkable. Even customers who already have the QX DAC fitted to their existing product will hear a vast improvement.”. He added, “We always try to foresee how a product might evolve, right from the concept phase. So it’s incredibly satisfying to be able to support our customers with such a superb upgrade option up to 10 years later.”

    Customers wishing to get their products upgraded will need to register via the website and will be given a position in the upgrade queue. When their turn comes, they will be given instructions on how to return their products to Cyrus, minimising the time they will be without their systems.

    The QXR DAC card upgrade is compatible with the following company products: 82DAC, 82DAC Qx, 8 DAC, 8 DAC Qx, 8 a, 6 DAC, 6a, 8 XP, 8 XPd, 8 XPd Qx, 6 XP, 6 XPd, Pre2DAC, Pre2DAC Qx, Pre DAC, Pre DAC Qx, Pre XP, Pre XPd and Pre XPd Qx

    The upgrade will cost £600 in the UK, although prices may vary slightly in overseas markets.
