Introduced at the AXPONA Audio Expo, the TEAC AI-503 is poised to be the centerpiece of your home Hi-Fi set up. Featuring an integrated60 watt-per-channel amplifier and USB DAC, the TEAC AI-503 supports DSD playback at up to 11.2MHz, as well as PCM at up to 384kHz/32-bit. This stylish unit also includes both optical/coaxial digital and RCA analog inputs, and an LDAC-compatible Bluetooth® receiver for high-resolution wireless audio listening. Finally, a combined 3.5mm optical digital/stereo mini jack on the front panel supports analog and digital connection of mobile devices and Digital Audio Players.
For personal listening, the AI-503 employs a dedicated Class AB headphone amp designed with both discrete push-pull circuits and op amps. Building on technologies developed for the industry-leading UD-503, this unique circuit design suppresses noise while maintaining the wide operational range of the amplifier. The AI-503 headphone output also uses a circuit design with completely separated grounding for left and right channels within the final 4-pole type jack. By completely separating the grounding of the left and right channels from the amplifier, channel separation is greatly increased and a much more transparent soundstage achieved.
Lastly, great care was taken during the industrial design of the AI-503 to ensure that the visuals are as stunning as the sonics. A solid metal outer case, specially selected potentiometers with aluminum knobs, and dimmable VU meters combine to deliver style and ease of use in equal measure.
