The AT-BHA100 headphone amplifier and AT-DAC100 D/A converter enable you to fully enjoy high-resolution digital sound sources, such as high-resolution audio, with balanced Hi-Fi headphones. Despite their compact size for desktop use, they support playback of high-quality formats such as DSD, reproducing even the finest details recorded in the sound source.

■Supports a wide range of high-quality formats
・Supports 768kHz/32bit (linear PCM) and 22.4MHz (DSD), allowing you to fully enjoy high-resolution sound sources.

■Uses high S/N and low distortion D/A converter
・The heart of the product is the AKM AK4452VN, which is well-known as a 2ch audio D/A converter, achieving high S/N and low distortion.

■Tuning that matches vacuum tube amplifiers
・Vacuum tube amplifiers have the characteristic that the high-frequency noise of the combined D/A converter affects the vacuum tube, making the amplifier's noise performance prone to deterioration. This product's unique tuning suppresses the high-frequency noise leakage of the D/A converter, achieving the high-quality playback that high-resolution sound sources inherently have. It is especially ideal for combination with the AT-BHA100.

■High-quality power supply

Equipped with a high-quality power supply made by Analog Devices, which has excellent distortion characteristics. By stabilizing the power supply, the D/A converter's original performance is brought out, and high-quality sound sources of a wide range of formats are accurately reproduced.

■Low distortion filter circuit
- The low-pass filter section after the D/A converter uses an audio-grade TI LME49860 op-amp with low distortion and good rise time. It reproduces resolution and low-frequency expression in a well-balanced manner. In addition, it combines with low-distortion and low-noise thin-film metal film resistors to realize a high-quality filter circuit.

■Nichicon chemical capacitors
- The chemical capacitors use capacitors made by Nichicon. They contribute to the audio low-frequency characteristics and lead to powerful bass reproduction.

■WIMA film capacitors
- The film capacitors are made by WIMA, which is renowned in the industry. They have smooth, low-distortion acoustic characteristics and achieve natural, clear sound quality.

■Supports various digital inputs such as USB-Type C?
- Two USB inputs (USB-Type C?/USB-Type B) and two digital inputs (optical/coaxial), allowing direct connection to various devices. Supports high-quality streaming and high-resolution audio source playback.

■External AC adapter
- To eliminate the effects of noise from the power supply, an external AC adapter with a separate power supply from the main unit is used. A large-capacity power supply unit ensures stable playback.
