The Teac AI-303 Hi-Fi stereo integrated amplifier powers two channels and connects to a TV via HDMI with ARC/eARC support. Its USB-C, coaxial and optical digital inputs support PCM and DSD file playback, while the USB-C input allows connection to a computer, smartphone or tablet. The built-in Bluetooth receiver supports LDAC, LHDC, Qualcomm aptX HD, Qualcomm aptX, AAC and SBC, as well as multipoint connection with up to two devices.
The Hypex Ncore power amplifier module is paired with a D/A converter featuring two digital filters and x2F, x4Fs and x8Fs conversion processing. The headphone output is four-pole and supports Crossfeed, while asynchronous USB mode uses the built-in clock to control signal timing.
