Power Supply Options

exaSound DACs are powered by external 12V power supply. The e68 uses 15 internal linear power conditioning stages in cascaded configuration. Every subsystem is powered by dedicated power source. This sophisticated power conditioning makes the e68 very insensitive to the quality of the external power supply.

The e68 DAC comes with a desktop style switching power supply included. Customers interested in using a premium quality linear power source have the option to order the e68 DAC bundled with a Teddy Pardo power supply. See above.
