KingRex UD-01 Pro USB DAC
Special Edition

NEW FOR 2011

The ultimate implementation of KingRex' UD-01: a fully discrete output stage, power supply upgrades, hard-wired solid silver interconnects, full cryo-treatment (and more) make this DAC the USB specialist at this price point.

The latest and greatest version of the groundbreaking UD-01 DAC: all new circuit board, revised output stage and, crucially, a custom on-board linear power supply - all for less than the cost of the original UD-01 and KingRex PSU.

Although limited to 16/48 playback, this sophisticated D-A converter is the perfect first step towards audiophile-grade computer playback of a digitised CD collection. Just add a USB cable.

The charm of the KingRex UD-01 has always been its unusual combination of musicality and resolution: it has a knack uncommon at this price point of nailing a recording's gestalt without digital artefacts. However, like any DAC, it's always needed a smooth, clean power supply to do its thing. Now it's in the box: a bespoke toroidal feeding Panasonic FM caps.

The audible benefits are striking: it's even better than the stock UD-01 + PSU combo: in particular the DAC gains brio and clout – it's a much more exciting listen than its junior sibling, yet nothing about this converter sounds forced: treble is naturally rendered in high resolution and the mid-range is pure, transparent and never pushy. Low frequencies have new-found credibility thanks to the improved supply to the dual mono op-amps.

Rather conveniently, the new all-black casework is roomy enough to accommodate some serious upgrades: see our unique Special Edition UD-01 Pro for details >

Although the on-board clock is well designed to minimise the effects of input jitter, all versions of the UD-01 are sensitive to incoming power corruption on the 5V USB line respond well to upgraded USB cables and power conditioners.
