ATC CDA2 MkII – CD Player /DAC/ Analog Line Stage



Winner Arizona Audio Video Club Speaker Fest 2019: ATC CDA2 Mk II > ATC P1 Stereo Amplifier > ATC SCM40 Passive Speakers.

A perfect companion to all ATC active speakers or any high performance stereo system. For those who want the best sound quality with minimum clutter, the perfect two piece solution: ATC CDA2 MkII > ATC Active Speakers.

“I was shocked when the ATC went head-to-head with my more expensive Shindo preamp and bettered it in some regards, and it worked very well with my tubed power amplifier. With ATC’s CDA2 Mk2 offering pleasing tonality, resolution, and dynamics, a versatile feature set, and rock-solid build, all for a decent price, it’s impossible not to crown it with the highest recommendation. It can provide a fine starting point for a solid high-end system.”

“The CDA2 Mk2 is well built, comprehensively equipped and highly revealing, but more importantly it makes familiar material engrossing, it makes you listen longer and dare I say it, louder. ATC has driven down distortion and noise so that more of the crucial timing and imaging cues can be heard, in the process they have delivered their finest digital product yet,” Jason Kennedy – The Ear Click Here for Full Review

“So as you’ve probably figured out by now, I ended up loving the CDA2 Mk II. It is a beautifully designed component that can do multiple things very well. It does a great job as a CD player, an external DAC, a headphone amplifier and a preamplifier. This might be a perfect buy for someone who is looking to simplify their life, or start delving into a great system without buying a bunch of equipment at once. Time and again I was surprised at how well it got to the heart of the music. I know that ATC designed the CDA Mk II with one of its self-powered speakers. Since I was impressed with their speakers in the past, I’m sure that it would be a dynamite pairing.” Paul Schumann – Enjoy The Music Click Here for Full Review
