Positive Feedback have published their review of LUMIN D1 on it's own and together with the Sbooster power supply.
They award LUMIN a PF Writers' Choice Award, 2016
During the review Maurice Jeffries writes:
the D1 captured that ineffable sense of airy openness that one typically associates, here we go again, with analog playback, not digital.
Lumin's diminutive D1 Network Music Player (with the outboard Sbooster PSU) has forced me to rethink what digital audio can do
The Lumin weds digital's traditional strengths (low noise, linearity, and absence of background noise) to many of analog's defining qualities (fluidity of presentation, overall coherence, musical flow, air and transparency) in ways that I have never experienced before.
