Accessible DAC With High-End Performance

Boasting comparable performance to top-of-the-line DACs, the Topping D20 DAC delivers true sound reproduction at a fraction of the price. Great for pairing with your desktop headphone amp, it’s based on a TI PCM1793 DAC and TI DIR9001 receiver with support for files up to 24bit/96—offering an instant upgrade for virtually any digital input. Plus, with front-panel input switching, it makes it easy to swap between USB, coaxial, and optical digital inputs on the fly. But don’t take our word for it, check out this Headfonia review for more information.
