Reviews

Headfonia Reviews - Quality audio reviews

"It's just about the most “complete” end-to-end product on the market in terms of having a source, DAC, amp, and interface combined in the one good-looking and great-to-interact with device - it's very much more than the sum of its parts if you're a full-sized headphone user and the idea of ​​having a source attached to your headphone amp sounds appealing, the ACRO CA1000 has enough genuine driving power to make it a viable desktop amp contender – it's the real deal."

  • ReplayGain for automatically adjusting the volume for different music titles
  • Silver plating shield to minimize noise and interference
  • With a display that can be adjusted up to 60 degrees, you can view your screen anywhere


Perfect driver for any headphone/IEM with 4 gain stages and up to 15Vrms output

In order to perfectly drive even the most demanding headphones, a device must be able to deliver an output that corresponds to the characteristics of the headphones.
The ACRO CA1000 supports 4 gain stages, so that almost every existing headphone can be optimally driven

The gain adjustment circuit implemented in the CA1000 can even drive high-impedance headphones without the sound quality being compromised by a maximum output power of 15Vrms.

The ACRO CA1000 unlocks the potential of headphones for a comprehensive sound experience.


Supports a wide range of inputs/outputs

The ACRO CA1000 features a variety of outputs that can be used by general users to audiophiles.

3.5mm, 6.35mm unbalanced, 2.5mm and 4.4mm balanced output jacks are available to connect a variety of headphones/earphones

The ACRO CA1000 can be used as a Hi-Fi audio system by connecting devices via a variety of digital inputs/outputs (optical, coaxial, Type-C USB) and analogue inputs/outputs (RCA).

All inputs -/Output settings can be easily and conveniently selected via the CA1000's touchscreen.

*There is a risk of headphone/earphone and hearing damage at high volume levels when used with headphones/earphones, so the gain level should be adjusted before the use.
*When two or more headphones are connected to the output, the sound is output from the last connected headphone.




Quad DAC with high output power and noise-free sound

ACRO CA1000 is equipped with four ES9068AS DACs, which provide perfect decoding capabilities with Astell&Kern amplifier circuit technology.
The clear and stunning output reproduces the original sound without distortion.
The 2.5mm, 3.5mm, 4.4mm and 6.35mm output circuits are physically separated through the use of tiny, independent relay components.

When the signal from each output stage of a high performance headphone amplifier is not correct blocked, noise interference may occur. The ACRO CA1000 provides noise-free output with an independent circuit structure by using relays to completely block unused ports.

32bit/384kHz, native DSD512 support
