Sold Waon this A-M-A-Z-I-N-G portable Dac/Amp at a meet on Nov 3, 2018 at the S.E. Michigan Headphone Meet. Brand new in box. Needs a home for someone on the go. It's really hard to believe the sound quality this little guy puts out! I have also decided to include iFi iDefender in original box at no charge. This allows one to break the ground out of USB port AND with the additional purchase ($49 from iFi) of the iFi iPower 5V, run extremely clean power to the DragonFly. Selling to save for HiFiMAN Ananda and because I already have a similar device portable dongle. Would make an excellent holiday gift/stocking-stuffer. New Retail price would be $199 + Tax. Save $90 of new list DFR + iDefender. First-Class Priority shipping included. Paypal only. Buy with confidence--seller feedback is impeccable!
