Lumin U1MINI

Only if your SSD does not require more than 0.5A. When using both USB storage and USB output, playback of high sample rate music may not be fast enough.

The preferred method is to connect the USB storage to a NAS or computer running MinimServer.
 
Probably, but we never tested it. Then there is the question of whether the wall wart for the hub would affect SQ...
 
Re: Lumin U1 MINI

Peter, I plan on the U1 since I have a great DAC. I have the Wavelet (DSP) from Legacy Audio that recommends the USB mini digital input for highest quality input.

Question: Is Lumin’s philosophy on their products that has USB output to utilize it before the other SPIDIF outputs?

Thanks
Andre

Hi, just a quick OT, if Ot is:

I want to lend my U1 mini to a friend for a few days: how can I not lose all my playlists?(If I hit "reset factory" ... that's what awaits me!)

Thanks!
Luca
 
Please save your current playlist.

The saved playlists reside in your iPad. Unless you're lending the iPad away too, the saved playlists are not affected by lending the Lumin hardware. To be safe, please make sure you have iCloud enabled for Lumin app. This way they are backed up and can be synced to multiple iOS devices.

I have just taken delivery of a Lumin U1 Mini. It replaces an Ultrarendu and Singxer SU6, both with linear PSUs. The Ultrarendu in turn replaced an SOTM trifecta.

Cold and straight out of the box, the U1 Mini is a small but noticeable improvement over the Ultrarendu/Singxer. I had both plugged directly into my Chord M Scaler and TT2, so I could switch between them to compare. I tried toslink, BNC and USB, although mainly use toslink since this sounds best in my DAC.

The difference is small, but the U1 Mini removes a small amount of “haze” around voices and instruments, and the background is just a little blacker and cleaner. I am hoping that difference increases with burn in.

Of course I am immediately thinking of replacing the internal SMPS with a linear PSU. But it sounds great as it is, and I like the idea of a single box (one reason I decided to replace my 4 boxes with the Mini), so may have to resist the idea unless there is evidence it is a real improvement.

It’s early days but so far I am very happy with the U1 Mini.

Hi Rossb, I am currently using the LUMIN D2 and recently bought an external DAC to improve the SQ. So I am planning to replace the D2 with a network transport/render. My friend suggested me to go get the Ultrarendu as the transport with the UpTone LPS. But I have been hesitating whether I should stick with the LUMIN U1 mini instead. I never have any experience on using the Sonore products. As I saw you mentioned that you used ultrarendu before but now plan to replace it with the LUMIN U1 mini, therefore do you mind to share what make you give up on ultrarendu and pick the U1 mini instead? What’s aspect make you think U1 mini can outperform the Ultrarendu. Many thanks

Not really. We have so many types of outputs (USB / AES / BNC / RCA / toslink) so that users can use the type that's best for the particular DAC / system / requirements / preferences.

For DSD64 it often requires USB, since not all DAC supports DoP over SPDIF. DSD128 and above always requires USB.
 
Hi Peter, I would like to know when comparing the U1 mini and U1; besides the external PSU on U1. What else are different in between the U1 and U1 mini, it stated it has a clock inside, are they both share the same clock? I am still considering if I should go for U1 or U1 mini, not sure if the technology on U1 is a bit outdated when compare to U1 mini as U1 has been out in the market for a few years already. Hope you can share your expertises idea for my reference. Many thanks
 
U1 MINI is a cost down version of U1, with three differences: LPS vs SMPS, heavy aluminium chassis, and DSD512 vs DSD256.

They use the same clocks.

Note: DSD512 and native DSD256 are meant for Linux native DSD compatible DAC only.

So, this, is intented for USB output only?
Version 2.03 (Apr 12, 2013)

Enhancements and fixes:


  • Added Invert Phase control

As Peter stated phase inversion is not supported for digital outputs, so it would only be applicable for analog outputs (which are not on the U1 or U1 Mini transport models.)
 
LEEDH PROCESSING.
Could explain a little how this system works.
I do not understand that if Lumin is at maximum volume this does not work.
