Description
PURE•DC is the ultimate power supply for Chord Electronics Mojo2 DAC, OPTO•USB, OPTO•DX or any sensitive low power audio component. PURE•DC is a passive all-analog design with the lowest possible ESR (equivalent series resistance), zero RF noise, instantaneous energy delivery and perfectly flat voltage regardless of transient load. In subjective tests with PURE•DC powered Mojo2 playing PGGB generated FLAC files, the sound proved to be superior to a battery or a regulated supply. PGGB’s high-frequency detail and low-frequency nuance was more fully revealed.
PURE•DC is ‘Semi-DIY’, based on the IanCanada UcPure MKIII control module and four(4) enclosed XL60 ultracapacitor cells for 12000F/13600F of storage. It’s available as a custom-chassis enclosure with a rear panel mounted PCB or an open-chassis (no enclosure). Recharging of cells is automatic and the optically isolated charger input has minimal impact on ‘pure’ mode operation. Hookup uses terminal blocks or barrel connectors and LEDs provide status. See the ucPure documentation here.
| Note: Recommended operation of PURE•DC with Mojo2 requires that the Mojo2 internal battery be disconnected. This forces Mojo2 into permanent desktop mode and relieves it of the RF noise generated from extra FPGA processing for battery management. |
