Hi-Fi News have published their review of LUMIN D2 (including a lab report) presenting it with their 'Outstanding Product' award.
During the review Andrew Everard writes:
D2 looks good, is sensibly priced and – thanks to a super-slick app – is a delight to use too
The D2 powers the bass anddrums along with real punch, while also rendering the instrumental andvocal lines with a wide-open sense of timbre and texture
In common with some of the higherend network players, it goes further than just delivering a recording, instead getting the listener into the heart of the music.
If you want the impression of real live musicians plonked in the room in front of you, the D2 delivers.
