Looking through solid Ayre: QX-5 Twenty internals & factory tour

Posted · Add Comment

Behind the Pono player’s seriously impressive sonic prowess were Colorado’s Ayre Acoustics. The Boulder-based company designed the circuit. And like all Ayre products, a balanced topology with all discrete components and zero feedback were applied without negotiation. The subsequent Codex DAC/headphone amplifier, an extension and refinement of Pono’s circuit, showed off just how Ayre’s adherence to certain design principles can make mains-powered headphone listening really sing.

Like many companies featuring within these pages, Ayre Acoustics are different with a Capital D. Marketing manager Alex Brinkmann describes Ayre as a twenty-three year old startup. It’s certainly true that they have held a robust reputation as purveyors of fine sound in the high-end audio niche for many years.

Those sniffing out Ayre on the back of Pono involvement might not be aware that their product range extends to some seriously high-performing power amplifiers, pre-amplifiers, a D/A converter, an A/D converter and a phono stage.

Earlier this year at the High-End Show in Munich, Ayre unveiled their latest product: the QX-5 Twenty is a Roon Ready digital pre-amplifier . A total of ten digital inputs and Gordon Rankin’s Streamlength™ code working the USB are tough to ignore. So too is the asking price: US$8995. According to Michael Lavorgna at AudioStream, you very much get what you pay for.

But sometimes, more than a minute or two is absolutely necessary. For Ayre Acoustics’ lead engineer Charley Hansen to talk us through the guts of the QX-5 Twenty, a full five minutes are required because a) it contains so very much and b) Hansen’s attention to detail is unsurpassed in the high-end audio industry:
