It’s an all-in-one device that can flex into a variety of positions, whether it be a DAC, amp, USB transport, standalone DAP – of course, where it really shines is when it’s all of those things at the same time. If you’re looking for an integrated desktop audio solution, ACRO CA1000 should be at the top of your list.
Introducing the Astell&Kern CA1000 Carriable Headphone Amp.
The ACRO CA1000 is a headphone amplifier that combines the functions and portability of a high-performance amplifier and DAP based on Astell&Kern's fundamental philosophy of delivering original sound.
In order to perfectly drive the most sophisticated headphones, a device must be able to fully deliver output that matches the characteristics of the headphone.
ACRO CA1000 supports 4 levels of gain settings so that almost any existing headphones can be driven to an optimal state.
3.5mm, 6.35mm Unbalanced, 2.5mm and 4.4mm Balanced output jacks are available to accommodate a variety of headphones/earphones.
The ACRO CA1000 can be used as a Hi-Fi audio system by connecting devices using a variety of digital inputs/output (Optical, Coaxial, Type-C USB) and analog inputs/outputs (RCA).
The ACRO CA1000 is equipped with four ES9068AS DACs, providing perfect decoding capabilities with Astell&Kern's amplifier circuit technology. The clear and overwhelming output expresses the original sound without distortion. 2.5mm, 3.5mm, 4.4mm and 6.35mm output circuits are physically separated by applying tiny, independent relay components.
The ACRO CA1000 features USB-PD 2.0 charging that supports 9V/3A for faster charging. When used with a USB-C adapter that supports USB-PD 2.0 fast charging, the ACRO CA1000 can charge to 50% in one hour, and fully charge in about 2 hours and 30 minutes.
Crossfeed mixes parts of the original signal from one channel and sends that signal to the opposite channel with a time difference to center the sound image.
Through the use of detailed settings such as Shelf Cutoff, Shelf Gain, and Mixer Level, you can set the level of crossfeed according to your listening preferences.
The latest Bluetooth version provides high sound quality with the convenience of wireless playback to headphones and IEMs. Bluetooth 5.0 features faster transmission speed, greater range and a more stable wireless connection when compared to Bluetooth 4.2. Both LDAC and aptX HD is supported to provide audiophiles with the best wireless sound possible.
The newly introduced BT Sink function connects the CA1000 to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker.
Music from an external device, such as a smartphone can now be played back in high-quality on the CA1000 using the BT Sink function.
