Up for sale is a 10/10 mint Sony ZX300+FDX1 (3hrs use on IEM, counter insanely low on ZX300) with original box, case box, case & matching otterbox for safe transport. I had purchased this for travel and the FXD1 for my wife, however with current events it's never left the house and hardly been used. It sounds amazing with the FDX1, which is an ideal pairing however this player is widely praised for easy pairing of IEMs and many full sized cans as well with balanced & high gain ability to drive.
Also included is a USB power/transfer cable and hard to acquire USB OTG adapter. I used this to interface with my Bifrost 2. YMMV as the dac has to be compatible. Price on this one is $550 for the combo. I'm seeing well used ZX300s still go for $350 with no accessories so I consider this priced far better than any listing out there. As such, price is firm. The FDX1 comes with all accessories and unused tips. Thanks for looking!
