Since their founding in 1999, Digital & Analog Co, Ltd. of Korea (known as D&A) has been providing some of the most highly regarded Class D Integrated Circuits to Original Equipment Manufacturer (OEM) Audio companies.  Taking advantage of their many years of experience designing and building the best measuring Class D amplifiers available, D&A began manufacturing their own line of high end audio components under the Calyx name beginning in 2008.

The Calyx line of audio amplifiers and Digital to Analog converters (DACs) have been stringently tested both objectively and subjectively in a wide variety of circumstances before being brought to market.  All the Calyx products feature unrivaled measured performance, class leading build quality and exceptional sound quality.

TheDigitalMusicExperts.com is very proud to include the Calyx line of USB DAC and Headphone Amplifiers in our product offerings.  You will find that we offer the Calyx products for sale individually, and also combined with a number of powered systems to operate as a complete digital music playback system.

We currently offer the Calyx Kong and Calyx Coffee USB DAC and headphone amplifiers for your enjoyment.
