iFi iDefender 3.0 in "as new" condition... tried it in various USB A locations with nice results. Definitely a great first step in tackling USB generated grounding noise...If your DAC is USB powered, the iDefender3.0 requires an external 5 volts to break the earth. It worked excellently with my iFi iPower 5 volt power supply (not included & listed separately) injecting clean power will ensure you get the maximum out of your USB audio. Only selling as I have slowly dismantled my second system due to an upcoming new house purchase and move. MSRP is $69.00, yours for only
$39.00
