This DAC sounds awesome and has some of the best measurements in the world. It's a good preamp as well.

I'm selling because I'm switching to a high-end all-in-one unit.

The warranty lasts until September 2023.

It comes with all the original accessories and packaging and is in pristine condition. (Except for the protective film that's still covering the screen.)

Price includes the PayPal fee and insured FedEx Home Delivery shipping. (United States only.)
