Still enjoy the odd Compact Disc, but embracing the convenience and lifestyle of streaming – ATC CDA MKII – a CD/DAC and Preamplifier from ATC.  Feed with a high quality server or streamer such as Innuos, and you are ready to connect to an active loudspeaker or power amp of your choice.


The all new ATC CDA MKII has been thoroughly redesigned from the ground up, to create a stunning digital source for you active or passive loudspeakers.

In September 2011 ATC launched the company’s first CD player, the CDA2, which combined a high end CD drive and outstanding pre-amplifier in one elegant integrated solution.

ATC began manufacturing electronics in 1982 but it wasn’t until 1996 that our first stand-alone product, the hugely capable SCA2 pre-amplifier, was introduced to market. Today, we are excited to announce the next generation integrated CD, Pre-amplifier and DAC – the CDA2 Mk2.

Details of its new features and improvements over the Mk1 model are as follows:

  • High resolution USB input capable of handling PCM data up to 384kHz and also DSD64, DSD128 and DSD256 (2.8MHz, 5.6MHz ‘dual’ and 11.2MHz ‘quad’ rates).
  • CD Player updated with a completely new TEAC transport.  This delivers faster play and seek times and much lower mechanical noise.  The new transport is also less susceptible to CD errors/damage/scratches (greater error correction).
  • New high-resolution DAC.  The new AKM chipset delivers lower nose and distortion and an optimised PCB layout brings further improvements to the convertor performance.
  • Power Supply – additional high-performance voltage regulators have been added – for a total of 9 – and their locations on the PCB optimised.  Local power supply decoupling has been further optimised from the Mk1, yielding additional improvements in performance, especially around the new DAC chipset.
  • Additional aux analogue input via 3.5mm mini jack with high input sensitivity for improved compatibility with low output portable devices such as phones and tablets.
  • All discrete Input and Output gain stages.  There are 6 common gain blocks, two for left and right input buffering, and four to provide a “true” differential output for the left and right channels. The positive and negative drivers are arranged in parallel to ensure that the positive and negative signal delays and phase shifts are identical.  The Output stages are configured as unity gain complementary compound (Sziklai) pairs, biased in class A.
  • Warranty on the CD transport extended to two years (previous Mk1 was 1 year).
