It features dual Cirrus Logic "CS4398" DACs and supports both 2.5 mm balanced and 3.5 mm unbalanced terminals. Despite its compact size, it boasts a soundstage and resolution comparable to higher-end models. ◎ Included Items ・Main unit (True Blue) ・DIGNIS AK70 leather case (Italian leather / in excellent condition) ・Original box, instruction manual set ※ Everything shown in the photos is included. ◎ Main Specifications ・Internal storage: 64 GB (+ microSD up to 256 GB *not included) ・Supported formats: FLAC, WAV, ALAC, AIFF, DSD64/128, etc. ・Playback time: Approximately 10 hours (manufacturer's claim) ・Size/Weight: Approximately 60 x 96 x 13 mm / 132 g ◎ Condition – Used only indoors, stored in a non-smoking environment – No noticeable scratches on the screen or body – Battery degradation is hardly noticeable ◎ Recommended Points The "wide and deep soundstage" during balanced drive is top-class in its price range.
