“Colorado-based Ayre Acoustics’ QB-9 DAC has been one of the company’s most successful ever products. It caused quite a stir when the first 24/96-capable edition hit the market back in 2009, and was lauded as one of the pioneers in enabling computers to become genuinely high-end music sources. Upgrades then followed in 2011 (24/192-capable) and 2014 (DSD) at which point the QB-9 was widely considered among audiophiles as the ‘killer app’ that offered the peak of computer audio capabilities. Fast forward to 2019 and thousands of QB-9s are still being played and enjoyed in homes and listening rooms all over the world. For many QB-9 owners, it remains their favourite piece of listening gear.”   

“The team at Ayre respects this and, as part of their commitment to providing customers with a lifetime of peak listening pleasure from their products, they are now releasing a brand new update for the QB-9.

The ‘Twenty’ update features Ayre’s latest innovations drawn from the new ‘8’ series of products, bringing the QB-9 right back to the cutting edge of audio technology and giving loyal QB-9 owners the thrill of rediscovering the finer details of their entire music library.
