FOSTEX USB DAC Headphone Amplifier with Support HP-A3mk2 Line/Digital Output, 32-bit/192kHz Hi-Res

ESS Technology's ES9016K2M DAC chip: The high-quality DAC chip supports a sampling frequency of 192 kHz, up from 96 kHz on the HP-A3. Enjoy superior sound quality without compromising ease of use. Analog circuitry for improved sound quality: To accommodate the increased sampling frequency, the analog circuitry has been newly designed, achieving improved THD (total harmonic distortion) and other performance levels comparable to those of higher-end products. [Added gain switch to support various playback sources] The headphone output amplifier gain can now be switched between two levels: HI and LO. The HI position increases the volume by 10 dB compared to the LO position. The HI position is effective for low level input signals and can be used with a variety of playback sources.
