TEAC AI-503-A Silver Integrated Amplifier w / USB DAC

Full Description

• USB Input

  

• aptX

  

• 384 kHz/32-bit

  

The AI-503 is an integrated amp and USB DAC that supports inputs up to 11.2MHz DSD and 384kHz/32-bit PCM. The DAC/preamp, which is the heart of the unit, follows the same design concept of our UD-503 and adopts a dual-mono circuit design that is fully balanced.

Separate VERITA AK4490 D/A converters - made by Asahi Kasei Microdevices Corporation - are used for the left and right channels. In addition to a USB digital input (for Windows/Mac computers), optical/coaxial digital input and RCA analog input, we have also enabled high-resolution wireless audio listening by including a LDAC-compatible Bluetooth® receiver. Furthermore, with a combined 3.5mm optical digital/stereo mini jack on the front panel, the unit supports wired, as well as wireless, input from DAPs.

The power amplifier uses a Class-D power amplifier (made by ICEpower a/s) that guarantees high resolution during the playback of delicate signals as well as high linearity at high volumes. This unit can power both compact bookshelf speakers (for desktop applications) and large floorstanding speakers.

High Capacity

Efficient toroidal-core power transformers that can supply stable power are used. They are specifically designed to suppress magnetic flux leakage and prevent electromagnetically-induced noise, so can provide current that is always pure and stable.

Dual Mono DAC

High-performance VERITA AK4490 DACs support 11.2MHz DSD and 384kHz/32-bit PCM. For the DAC chips, the key to high-performance digital audio, we used the highly-regarded VERITA AK4490* DACs, made by Asahi Kasei Microdevices Corporation. Along with native playback of 11.2MHz DSD signals through direct processing, a wide range of high-resolution audio sources (including 384kHz/32-bit PCM digital input) are supported.

Robust Design

All-metal enclosure provides both vibration resistance and a stylish appearance in an A4-sized footprint that can be easily accomodated. Since the enclosure is completely made of metal panelwork, which is resistant to external noise, the infiltration of electromagnetic noise generated by computers and other equipment is well-suppressed. This creates an electrically ‘clean’ internal environment with little noise.

USB Input

The USB input supports resolutions up to 11.2MHz DSD and 384kHz/32-bit PCM. “DSD native playback” in which DSD is converted directly to analogue without first being converted to PCM is also supported. TEAC HR Audio Player, a free music playback software specifically written for TEAC products, supports ASIO 2.1 and DoP (DSD over PCM) formats, allowing native playback of 11.2MHz DSD audio sources on Windows as well as Mac computers.
