“The Nano iDSD BL has a natural sounding tonality with a presentation that is easy going and slightly euphoric, especially in the vocal and instrumental timbre. Its staging is fairly open and spacious with excellent width and some decent depth and height but not the most extended. Instrumental separation in particular benefits from that open sound and black background the BL is able to project.

There are some nuanced differences that the filters bring to the sound of the BL. The listen filter adds a little more low-end warmth, particularly in the mid-bass and pulls back a bit more on vocal and treble presence. The reduction of higher frequency levels produces a very smooth and euphoric sound with good low-end body.”
