✓ 1 Year Warranty included
✓ Authorised UK Dealer
The Astell&Kern ACRO CA1000T combines a powerful headphone amplifier, high-resolution music player and versatile audio hub in one premium desktop-friendly system. Its dual ESS ES9039MPRO DACs and triple amplifier design let you switch between OP AMP, TUBE AMP and HYBRID AMP modes to suit your listening preferences. With up to 15Vrms output, support for PCM up to 32-bit/768kHz and native DSD512, plus Wi-Fi, Bluetooth and extensive analogue and digital connections, the CA1000T is built for serious headphone listening at home or in the office.
Choose the Sound That Suits You
The CA1000T's Triple Amp System offers OP AMP, TUBE AMP and HYBRID AMP modes. OP AMP mode focuses on clarity and dynamic presentation, while the dual KORG Nutube 6P1 valves introduce a warmer, more analogue character in TUBE AMP mode. HYBRID AMP combines elements of both approaches, giving you another way to tailor your listening experience to different headphones, recordings and personal preferences.
Flexible Output for a Wide Range of Headphones
With four selectable gain levels and up to 15Vrms balanced output, the CA1000T is designed to accommodate a broad range of headphones, including demanding high-impedance models. Its 3.5mm and 6.35mm unbalanced outputs sit alongside 2.5mm and 4.4mm balanced connections, giving you the flexibility to use different headphones and earphones without needing a separate amplifier for each.
Streaming, High-Resolution Playback and Extensive Connectivity
The CA1000T supports PCM audio up to 32-bit/768kHz and native DSD512, with 256GB of internal storage and microSD expansion up to 1TB. Dual-band Wi-Fi enables network playback and compatible streaming apps, while Bluetooth supports LDAC and aptX HD. Analogue RCA and XLR outputs, digital inputs, USB DAC functionality and a built-in rechargeable battery make it a flexible centrepiece for a personal audio system at home or in the office.
