Second-generation version of the original CDA2 from 2010, and developed as the ideal partner for the ATC P2 power amplifier and active speaker designs, the CDA2 MK2 CD / DAC / Pre-Amplifier combines convenient USB access to up to 24/384 kHz PCM/Quad DSD high-resolution music streaming with an upgraded CD transport and a premium 32-bit DAC.

CDA2 also offers dedicated headphone amplification and wider input selection, along with analogue circuits redesigned for an even wider, flatter frequency response with very low distortion.

ATC have also announced that on 21st February 2021, the CDA2 MK2 received Roon Tested certification from Roon Labs. All Roon Tested devices are profiled by the Roon QA Team so that Roon can identify them and automatically configure its settings to optimal. This means that you can just plug them in to the CDA2 MK2 and know you will be able to enjoy the best in high-performance audio.

Roon transforms the experience of browsing music. Artist photos, credits, bios, reviews, lyrics, tour dates, and composers are located automatically, then interconnected by links to build a surfable, searchable digital magazine about your entire music collection.

Roon also links all of your personal files with the millions of tracks available on TIDAL and Qobuz, so you can start with the music you know, then explore and discover new music from the world beyond your collection. Roon runs on most Mac, Windows, and Linux PCs as a server, with an Android or iOS smartphone/tablet used as a control point.

Made in the UK, CDA2 MK2 is supplied with IR remote control and is covered by a six-year warranty.
