Features
- Support for 768 kHz, 32-bit (linear PCM) and 22.4 MHz (DSD) audio lets you fully enjoy these high-resolution sound sources
- A two-channel AKM AK4452VN converter offers a high signal-to-noise ratio and low distortion
- Unlike conventional DACs, the AT-DAC100 is specifically tuned for vacuum tube preamplifiers – it suppresses high-frequency noise output for precise playback of high-resolution sound sources
- High-quality Analog Devices power supply provides the stability to ensure accurate reproduction of the sound source
- Audio-grade Texas Instruments LME49860 operational amplifier offers low distortion and superior attack performance, resulting in a perfect balance of high-resolution and low-frequency content
- Operational amp is combined with a low-distortion, low-noise metal thin-film resistor to create a high-quality filter circuit
- Nichicon chemical capacitors contribute to the low-frequency characteristics of the audio, leading to powerful bass
- WIMA film capacitors create smooth, low-distortion sonic characteristics for natural, clear sound
- Two USB inputs (USB-C and USB-B) and two additional digital inputs (optical and coaxial) enable connection to a variety of devices
- Compact unit can be set up vertically or horizontally
- Â
- Large-capacity external AC adapter separates the power supply from the main unit for reduced noise
