Pretty rare beast in such flawless condition and perfect workability nowadays! Selling one of the coolest DAPs I have owned. Amazing reference-like sound quality. Used it with hi-end earbuds and with BQEYZ Summer. It has neutral sound signature, have lots of power to drive majority headphones, resolution and detailization is pretty high. No picks or falls were detected - very balanced sound without missing anything. I would say it sounds very academic-like, but at the same time very alive and not boring at all. It is pretty analytical, but yet does not lose musicality. Scene is built in the way: listener sitting in the big hall on 1-5 row. It has balanced and unbalanced inputs. Also it works great as external usb-dac. Opus 3 can be easily the choice for the one who search for the one and only dap in the set-up.

Condition is like-new. On the display put protective coat. You get box, papers, usb-cable, leather case in like-new condition and the opus 3 itself. No issues with battery, buttons, wheel or whatsoever.

The reason for sale is gradually selling all my audio toys...auidiophilic journey comes to the end) You can offer something for trade. (I do not know what can be interesting for me, but who knows...).
