“Smooth delivery of orgasmic sound. Powerful enough to drive a planar, whilst gentle enough for sensitive IEM…the iDSD BL presents a harder bass kicks in the opening, overall enhacing the imaging and musicality of the song….The iDSD BL brought Norah Jones directly to my room. The darker Black Label makes her voice sound as smooth as honey….The notes from the double bass and piano was well rounded and punchy which added some depth to the sound….I would call this unit a more matured iDSD with minor refinements that makes it great….The iDSD BL would be more polite to most songs, and also able to satisfy your inner bass-head…”
Many thanks aftercrasher!
