Ayre DAC QB-9 upgrade

... Audio Magic, who has been recently appointed as the new Australian importer for Ayre Acoustics products, has announced the local availability of the company’s ‘Twenty’ upgrade for existing QB-9 DAC owners.

Aligned with Ayre Acoustics ideology of long-term customer satisfaction and product longevity, the latest ‘Twenty’ circuit upgrades make for substantial improvements to the very popular QB-9, now to be known in its new livery as the QB-9 Twenty.

The list of updates and circuit advancements is extensive and includes Ayre Acoustics’ new JFET differential stage which lowers the noise floor and a proprietary ‘Diamond’ output circuit which is said to improve “musicality and bass response”. Further improvements feature a redesigned AyreLock power supply regulation circuit, a new AC noise filtering scheme said to enhance the resolution, custom-designed ‘Ayre Asynchronous’ USB technology which further reduces electrical noise and ties in with proprietary re-clocking to eliminate USB domain jitter.

A new ESS DAC chip improves signal-to-noise ratio and is said to deliver performance benefits while extending PCM payback to 384 kHz. Native DSD is catered for at up to DSD256. Not so common these days is the allowance for HDCD decoding.

The new upgraded QB-9 Twenty is available in August 2019 via Audio Magic’s dealer network around Australia.
