Video Review


The iFi micro iDSD Signature is an absolute delight to use. Music comes alive with any pair of headphone or IEM that you care to throw at it. The musical experience feels like the headphones disappear on your head, leaving just the music floating around you. Bass is fast, tight and controlled. Mids and exquisite. Treble is excellent too. Superb soundstage.



The iFi iDSD micro signature is my personal favourite headphone amp DAC. 9.5/10.
