For sale is my iFi Nano iUSB 3.0. Please note that this is not a DAC. This is used to feed clean USB power and signal to USB DACs. These are no longer in production and hard to find new. I most recently used it to power and clean the signal to my Chord Qutest. It works especially well in that regard. I've since sold the Qutest and no longer need this since I'm focusing on cheaper DACs. I am the original owner and purchased it in late February. All original accessories, box, and sleeve included. It sold new for $220. I am asking $175 shipped. Please note that I do not have Paypal. Zelle or Google Pay is preferred. I've also used Square cash app in the past. Thank you for any interest.
