Xuelin H7 DAC/Amp

A do-it-all DAC/amp for the mobile listener, the H7 from Xuelin fits an extensive range of high-performing hardware into a sleek form factor. Handling digital-to-analog conversion, two ES9038Q2M chips achieve a wide dynamic range alongside an ultra-low 112-decibel signal-to-noise ratio and 120-decibel THD + N level. The USB interface is an SA9227 asynchronous clock, which delivers precise timing while all but eliminating jitter. On the analog side, OPA2134 and AD8397 amps combine to deliver high-fidelity amplification with enough power to drive any pair of headphones. Switch between 3.5-millimeter single-ended and 2.5-millimeter balanced outputs to fit your needs—and listen for hours on the go, thanks to a 2,900-milliamp lithium battery.
