ATC HIFI CDA2 – CD Pre-Amplifier
- All-discrete class-A pre-amplifier with balanced and unbalanced outputs.
- Two analogue inputs via RCA/phononand one via 3.5mm mini-jack.
- High performance CD Player.
- Premium AKM 32-bit DAC.
- USB digital input supporting up to 384kHz PCM data and native DSD256.*
- Headphone amp featuring discrete output stage.
- Handmade in England.
- 6 year warranty.**
*DSD256 support via PC only (up to DSD128 via Mac).
** TWO years on CD mechanism.
- 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.
