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. Official product page: https://ifi-audio.com/portfolio-view/nano-iusb3-0/ I most recently used it to power and clean the signal to my Chord Qutest. It works especially well in that regard. However, I made some short-term poor financial choices, and I'm selling some of my smaller equipment so that I can justify keeping the Qutest for the longer term. I am the original owner and purchased it in late February. All original accessories, box, and sleeve included. It sells new for $220. I am asking $175 shipped. Please note that I do not have Paypal. Google Payments is preferred. I have used it with my past several sales with no issues. Thank you for any interest.
