Astell&Kern further improved TERATON ALPHA using knowledge learned from the designof the Hybrid Tube System found in our SP2000T and the noise removal from the CA1000. TERATON ALPHA, engineered through endless research,is Astell&Kern's unique technology that has been designed to produce audio playback that is as close to the original sound througheffective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface.4-levels of gain and up to 15Vrms output for the Perfect Head-Fi SetupTo 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.Upgraded Sound The world's first Use of the Newest ESS Flagship DACThe ACRO CA1000T is designed with dual ES9039MPRO, using the newest flagship DAC from ESS for the first time ever to offer more vivid and voluminous sounds that surpass your imagination. The ES9039MPRO is an additional ES9039PRO model that has a built-in stereo hardware MQA renderer. It has even more advanced modulation than the existing flagship DAC to reduce power consumption, noise and distortions inside the DAC for enhanced audio performance. Astell&Kern invented and optimized a new design of amp block to heighten the performance of the ES9039MPRO, allowing it to offer more balanced and intense sounds with deeper and richer bass sounds and clear highs.Sound Design by DAC FilterWith the ACRO CA1000T, you can pick and choose from seven DAC filters to create your own sound style.Design your own sound with the seven DAC filters.Full Balanced Circuit with Dual-TubeThe 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 TechnologyThe 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 provides 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.Extreme clarity and dynamic Uniquely warm and musical A fresh combination of retro vibes and high-resolution output.Custom design to minimize microphonic noiseA special custom design minimizes microphonic noise that may be caused by external shocks and vibrations. To address the structural issue of vacuum tubes, where microphonic noise is created even by the smallest shocks or vibrations, we repeatedly developed new designs and conducted thorough reviews and testing during prototyping. Both sides of the vacuum tube are fixed with flexible silicon covers to minimize shocks and a magnetic force is used to physically separate it from the PCB, offering greater stability and isolation when the tube is operational. Astell&Kern is committed to designing these small elements and aspects that create the unrivaled differences between our products and the sound of competitors.* A patent application has been made for this technologySeparation Using Magnetic PolarityFlexible Silicone CoversCrossfeed, Speaker effect when listening through headphonesIn a headphone environment in which the left and right channels are clearly separated, ear fatigue may increase during prolonged listening. The moment you turn on Crossfeed, the experience of crisp, but comfortable sound begins. 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.Optimized device care with USB-PD 2.0 charging and battery protection modeThe ACRO CA1000T supports USB-PD 2.0 charging with 9V/3A and provides 11 hours of continuous playback when fully charged. Due to the long-term connection to the power supply while connected to various audio devices, long-term charging can shorten battery life. The ACRO CA1000T has a battery protection mode feature that helps extend battery life. When battery protection mode is enabled, the battery is charged up to 85%, and then the charge stops. If the battery drops below 80%, the battery will start charging again and charge up to 85%. Enjoy the ACRO CA1000T's powerful sou...
