Phenomenal Soundstage, Imaging & Clarity

Praised by Recording MagazineTape Op Magazine, Creative Sound Lab, and more, the H2 Designs MIYO DAC/amp is popular among those who need a high-quality portable monitoring solution for their full-size headphones. It has a sophisticated USB-bus power design with eight separate low-noise regulated supplies. For clocking, it uses state-of-the-art MEMS oscillators with very little phase jitter and incredible accuracy. The result? A huge soundstage, precise imaging, and clear, virtually noiseless performance. And the MIYO looks every bit as clean as it sounds, with a solid machined-aluminum build and no unnecessary modes or buttons. Two headphone jacks double as digital outputs and also incorporate optical ports.
