ATC CDA2 MKII

Description

CD Player/Pre-amp/DAC

• Hand built in the UK
• Ultra-low noise discrete design
• New high-resolution DAC.  The new AKM chipset delivers lower noise and distortion and an optimised PCB layout brings further improvements to the convertor performance.
• 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).
• 2 x analogue inputs, including additional aux analogue input (on analogue 2) via 3.5mm mini jack with high input sensitivity for improved compatibility with low output portable devices such as phones and tablets.
• 2 x digital inputs
• 6 year warranty (excludes CD mechanism which is covered by a 2 year warranty)
