Ayre Acoustics provided the engineering nouse for Neil Young’s Pono player, which later informed the company’s first dedicated headphone amplifier: the Codex.
Founder Charles Hansen’s fundamental design principles include the use of in-house- minimum phase filters, fully discrete analogue output staging and absolutely no global feedback.
Those very same design principles can be found at the heart of the Colorado company’s newest high-end ‘digital hub’, the QX-5 Twenty, which also features one of ESS Technologies’ latest D/A converter chips – the ES9038PRO. Ayre’s minimum phase filter is implemented here by way of an FPGA.
For its data clocks (oscillators), Ayre collaborated with Russian manufacturerMorion. “A specially developed new doubly-rotated cut quartz crystal allows a high level of performance to be achieved without the need for expensive temperature-controlled ovens,” reads the press release accompanying the QX-5 Twenty’s launch.
