Now with Roon Certification

Adding to ATCs exceptional range of standalone audio electronics, we are very happy to announce the release of the new and improved CDA2 Mk2 CD/DAC/Pre.  There have been comprehensive changes from the Mk1 model leading to improved audio performance and usability.  From the outside, the product looks very similar but internally every area of the product has been re-designed or optimised.

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).
