AI-303 Integrated Amplifier/DAC
Exceptional sound quality and powerful performance easily integrate into minimalist setups with a wide variety of connections.
Light Footprint, Major Connectivity
This micro-size hi-fi amplifier will integrate perfectly into smaller listening spaces. Popular audiophile connectivity options include CD Player, tape decks, turntables, and more.
State-of-the-art Circuitry
TEAC products are built by and for audiophiles. The AI-303’s ESS Saber 32-bit digital-to-analog convertor (DAC) allows for DSD256 (11.2 MHz) native playback and pulse-code modulation (PCM) 384kHz/32-bit high-resolution sound sources. With full MQA decoder built-in, your highest res file formats such as FLAC and WAV will playback with all the quality and depth of the original recording.
The Best for Bluetooth® Streaming
Experience the highest sound quality with wireless playback compatible via Bluetooth Qualcomm® aptX HD™, LDAC™ and LHDC codecs. The AI-303 supports multipoint connection for two-source device pairing, and memory capacity for up to eight devices.
High Efficiency Class-D Amplification
Fitted with a 50W + 50W Class-D power amplifier module manufactured by Ncore and fine-tuned by TEAC engineers, the AI-303 reduces distortion while packing tremendous power in a compact design.
For Audiophiles…
Who Still Binge-watch
Because we know minimalist spaces are often multifunctional, the AI-303 also includes an HDMI port for eARC/ARC connections. Connect to your TV, Klipsch in-wall speakers, sound bar, etc. and control everything through your TV remote.
Crossfeed Control for Hi-fi Headphone Use
With a dedicated headphone amplifier and crossfeed knob, you can customize your listening experience by separating sound in your headphones. A great way to experiment and enjoy both stereo and mono at your leisure, all through one device.
Metal Chassis, Minimal Resonance
Skip the plastic. Full metal housing provides both excellent vibration control and a sharp, classic look. TEAC sources high-quality metal componentry for minimal resonance and the cleanest sound.
