The Aurender A10 meets the world as a sleek but substantial (22.5 lbs.) component in a beautifully machined aluminum chassis. On its front panel, from left to right, are a square power button (it flashes when the A10 is powering up or down), a 3" AMOLED screen, a group of four buttons to control playback, and a hefty rotary volume-control knob that brings up both numerical and meter-like graphic representations of the level set by turning the dial. A modest-sized remote (6-3/4" x 1-3/8" x 9/16") with surprising heft duplicates the functions on the front panel, plus allowing muting and choice of digital input. In back, there’s a standard IEC receptacle for the power cord, a rocker switch that makes the front panel power switch operational, an optical digital input, a USB output, and both unbalanced (2Vrms) RCA and balanced (4Vrms) XLR analog outputs. Inside, the digital electronics are on one side of the chassis, the DACs and analog output stage on the other, to help protect the converters and other sensitive circuitry from electronic noise. Power supplies are robust, with four toroidal transformers individually supporting key components of the computer’s architecture. Measured jitter is low, below 100fs, thanks to a clock generator based on field-programmable gate arrays (FPGAs). A pair of the well-regarded AK4490 VERITA chips accomplishes digital-to-analog conversion.
