KingRex UD-01 USB DAC

NOW SHIPPING WITH IMPROVED POWER SUPPLY!

Representing a significant step up from the Digital-Analogue Converter built into the KingRex T20-U amplifier and the tiny SuperPro DAC, the petite UD-01 delivers a strongly musical 'non-digital' presentation thanks to the (TI) Burr-Brown OPA2604 which acts as an output stage preamp and a design that completely omits coupling capacitors.

The primary chip is the Burr-Brown PCM2702E mated with a large internal buffer for audio packet storage, effectively re-clocking the input stream. The UD-01 delivers everything in spades: timing, soundstage, resolution – yet never sounds dry or squeaky-clean like the majority of low-end DACs. Rather, it is weighty, mellifluous and coherent. Though it's a cliché, this DAC delivers a sense of musical 'rightness' normally associated with much more expensive converters. This really is a DAC without flaws: extremely well articulated bass, smooth and natural midrange and a detailed top end – all beautifully balanced.

Though performance out of the box is impressive, this chunky aluminium-clad gem has an ace up its sleeve: the DC input socket enables it to be paired with a wide variety of upgraded 12V power supplies, like the literally transformative KingRex PSU. When combined with an upgraded USB cable, this combination rivals or betters any sub-£400 DAC currently available, almost all of which are limited to inferior power stages. In auditioning, we've strugged to find anything that sounds this good in 16-bit under £500. Look out for bundle offers and upgrades, including our unique Item Special Edition version . . .
