While the XDP-100R is beautifully designed and a stellar performer, the DP-X1 brings more hardware refinement, features, and power to the plate. The Pioneer, for example, has one DAC and one amplifier for both channels. The Onkyo takes things up a notch, with dual ESS Sabre ES9018K2M DACs and dual ESS Sabre 9601K amplifiers. Each DAC and amplifier is dedicated to its own stereo channel for the highest possible fidelity and headphone performance. Consequently, the Onkyo is capable of supplying 150mW + 150mW of power and support headphones from 16Ω to 600Ω with balanced connections.
