It's an all-in-one Head-Fi audio system that provides great connectivity with external audio devices and speakers thanks to its diverse range of input/output ports, allowing you to easily enjoy network audio playback and music streaming.
Extensive Input/Output Options
The ACRO CA1000T offers an extensive range of input/output options that can meet the needs of audiophiles looking to build their ideal
Head-Fi system with maximum utility.
For greater ease of use, you can change the input/output settings using the touch screen on top of the product while multiple cables and
devices are connected.
1. 3.5mm, 6.35mm Unbalanced, 2.5mm 4.4mm Balanced Output
The output port located on the front side of the product is compatible with a range of sizes so that various headphones and IEMs can be connected, including both low-impedance and high-impedance varieties. The 3.5mm port may also be used as an optical output.
2. Mini XLR, RCA Output
Balanced Mini XLR and Unbalanced RCA output with circuits that minimize noise and distortion offers the best sound to the amp and external audio devices through lineout, so that it can effortlessly support active speakers as well as a desktop Head-Fi sound environment.
3. 4.4mm, Coaxial, Optical Input
ACRO CA1000T can receive signals from various external devices via its coaxial and optical digital inputs as well as a 4.4mm analog input, so that users can build their perfect audio system. Receive digital and analog signals from an external DAC, interface, and external source devices and use them with the convenient integrated CA1000T system. Enjoy the powerful output and dual-tube sound with any device of your choice.
4. USB Input, Bluetooth, Wi-Fi
ACRO CA1000T supports Type-C USB DAC functionality. Enjoy perfect sound from both Mac and Windows PCs, as the CA1000T can play ultra-high quality sound sources.
In addition to this, it supports network play such as AK Connect and Roon Ready, as well as various streaming apps through high-quality Bluetooth and Dual-Band Wi-Fi, completing a perfect all-in-one Head-Fi audio system for audiophiles.* Roon Ready function will be released through a firmware update.
4-levels of gain and up to 15Vrms output for the Perfect Head-Fi Setup
To run the most detailed IEMs and most demanding headphones perfectly, an output that matches the characteristic of the receiving device is required. The ACRO CA1000T supports 4 gain level settings so that almost any headphones can be driven to an optimal state.
The 4-levels of gain setting can create the ideal output for a device’s characteristics and sound, allowing users to fine tune and dial in their desired volume output. And with up to 15 Vrms output, it can run high-impedance headphones with ease.
The output ports' electrical capacity has been raised to add stability when operating devices with different impedances at the gain level setting, and the separate balanced and unbalanced volume controllers optimize electricity flow and reduce noise for the best sound.
With the ACRO CA1000T, you can enjoy optimal device performance and pure sound that touches your heart.
Full Balanced Circuit with Dual-Tube
The ACRO CA1000T has dual Twin Triode KORG Nutube tubes, which were implemented for the first time in our award winning SP2000T, offering advanced tube sounds.
When a product is equipped with a Dual DAC, and one vacuum tube there must be a separate circuit to convert the signal to Balanced right before the output terminal. This structure requires a process to convert an unbalanced signal to a balanced signal, during which, noise gets amplified in the process.
The CA1000T, however, offers a complete balanced circuit that separates left and right channels with two vacuum tubes, creating even more natural and softer sounds.
Both Tube AMP mode and OPAMP provide a powerful 15 Vrms output, and the headphone ports allow you to enjoy the unique sounds of vacuum tubes without any limitations.
TRIPLE AMP SYSTEM is the Next Generation of AMP Technology
The ACRO CA1000T exceeds the standard approach to AMP Mode selection, based on the type of music you are listening to.
Select between TUBE AMP mode, OP AMP mode, or the brand-new HYBRID AMP mode.
OP AMP mode puts Astell&Kern's AMP technology expertise to use, delivering extreme clarity and dynamic sound,
while TUBE AMP mode prov ides a uniquely warm and musical sound.
HYBRID AMP mode - a first for digital audio players - enhances the resolution and clarity of the existing TUBE AMP mode to express more musical detail.
HYBRID AMP mode, combines the advantages of retro analog performance and high-resolution output, giving you the pleasure of a brand new tonal characteristic.
Experience the unique sound enhancements that this AMP technology has to offer.

Testimonials
Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.
James F.
Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.
The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!
Guy H.
I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.
