Reassuringly engineered linear regulated power supplies for 12V audio applications. Nominally declared at 12V, the PSUs actually output 13V and have been designed specifically to match the KingRex T20U amplifiers. However, our customers report a diverse range of successful applications of these supplies: from Tripath amplifiers and 12V DACs to the Acoustic Revive AR-77.

Some may balk at spending as much on a power supply as on their DAC or amplifier, but in reality, 'twas ever thus: by far the most expensive and influential part of any amplifier is the power supply, and digital-to-analog converters are equally sensitive to clean, well regulated current. What's wrong with the free power brick, then? Allow the good people of 6 Moons to demonstrate, as part of their recent review of the KingRex Sealed Lead Acid Powerpack:

In typical operation, the standard switch-mode 'brick' is injecting lashings of audible distortion into the signal path. The outstanding performance of the KingRex SLAP is one good reason why it is relatively expensive.
