Lumin U1 Music Transport – An S1 without the DAC

Testimonials (on all Lumin products)

Product of the Year Award – The Absolute Sound (Upper End Music Server of the year)

“Had I not known better, I would have sworn I was listening to mastertapes. It was an impression of resolution, soundstage integrity, and clean transient speed… reaching a level of musicality that will make even diehard analog fans forget its computer roots.”
– Neil Gader, The Absolute Sound, (read the review)

“The network player by which all others should be judged… the most polished network player I’ve ever used.”
– Computer Audiophile  (read the review)

Six Moons “Blue Moon” Award

“To me the S1 is one of the most attractive one-box digital contenders I’ve had opportunity to hear. Perhaps the greatest strength of the S1 resides in a kind of sonic and functional coherence that I do not find with potential competitors… The LUMIN S1 to my ears combines the rare ability of sounding pristine, precise, warm and rhythmically involving all at once… The LUMIN S1 delivers an enormously appealing and involving musical presentation which will become my new reference as a still-affordable digital front-end to consequently demand a Blue Moon award.

“The more time you spend with the LUMIN, the more it becomes clear that the strong performance with a wide variety of material, the extremely well thought out app, and the very handsome appearance combine to make the LUMIN a very enticing buy and one that should work well in a variety of systems.”
– Ed Selly, Hi-Fi+

“Its sound is crisp, clear and detailed with an engaging sense of timing that draws the best from the music …the app is one of the best out there on any streamer I’ve used so far.”
– Jon Myles, Hi-Fi World March

“Each recording was so absorbing, that I did not want to interrupt any album I listened to from beginning to end …This is the most analogue digital player I have ever listened to
– Audio Stereo (read the review)

“…in my opinion it stands up to all comers. I spent many hours listening to the Lumin and every time found my toes tapping. I’ve played the saxophone for over 30 years and at the end of my listening sessions, I found the Lumin sounded more like music and less like computer!”
– Mike Bovaird, Founder, Audio Shark Forums
