Ayre Codex Headphone Amplifier/DAC/Digital Preamp

Item # AYR-CDX
test
$1,995.00

“I don't know if it's due to the "zero negative feedback" design or the killer digital filters Charlie Hanson dreams up, but with file resolutions of PCM up to 32/384 and DSD128 the Codex is just plain musical. Can't wait to get one up here for a long hard listen.”

– Tyll Hertsens, innerfidelity.com

"When I first began reviewing the Codex, I thought that I would be experiencing a fine headphone amp with a DAC included as an extra feature. What I discovered was that the Codex is a first-rate DAC that sounds as good as or better than DACs costing far more in price. The Codex can easily form the basis of a first-rate high end system...I feel that Ayre has accomplished something very special in the design of the Codex that will force other DAC manufacturers to improve their products or fall behind. Given the price, performance, and features found in the Codex, I feel it is the most significant product I have reviewed in 2015."

- Steve Plaskin, audiostream.com

Built in Boulder, Colorado, the Codex is Ayre’s most affordable and versatile product. It performs equally well as a stand-alone headphone amp, DAC and digital preamp. As a headphone amp it offers the latest state-of-the-art technology for which Ayre Acoustics is so well known. This includes featuring dual 3.5mm mini jacks that can be configured for balanced mode headphone listening, a fully-balanced signal path throughout the analog circuit that provided a whisper quiet background, Ayre’s exclusive diamond output circuit and a audiophile grade linear AyreLock power supply. When combined with their zero negative feedback design and minimum phase digital filter, the Codex provides pure musicality that is almost hard to believe and unheard of at its price. The Codex can also be used as a standalone DAC with fixed output and/or as a standalone digital preamp if you need a volume control. Whether being used as a headphone amp or as a part of a high performance home stereo, the Codex is an astounding achievement and is already one of our choices for product of the year. If you’re looking for a headphone amp or a new DAC, the Codex will definitely make a great addition to virtually any system. Ayre has been designing products like this for over 20 years. Listen and experience what Ayre and your music are all about.
