In Germany there was a moderate (considering the cost explosion of chips and other material these days) price increase from € 2,200 to € 2,500. Don't know about the US market.

Re: Lumin U2 Mini
If I am using the DAC from Anthem AVM 90 does it make sense to sell my Lumin T2 and buy the U2 Mini Thanks

Re: Lumin U2 Mini
Hi,
This is my first post in this forum , i am very interested in this streamer because of the DSD 256 up-sampling ,,, any feedback regrading this feature,
also i suppose it do native DSD output ?
Thanks in advancd
-
June 13, 2022, 02:18 AM #12
Re: Lumin U2 Mini
Lumin (and Linux) native DSD compatibility is dependent on the USB controller and the firmware inside the DAC.
Which DAC are you using?Peter Lie

Re: Lumin U2 Mini
I am planing to use it with AudioGD DI20HE connected to AudioGD R7 through I2S ,, if Lumin U2 Mini is better i may connect it directly to the R7 Dac through the USB
It use Amanero Combo 384 USB Interface
-
June 13, 2022, 09:27 PM #14
Re: Lumin U2 Mini
Unless you have manually upgraded the DI-20HE Amanero firmware to 2006be10 or later, DSD256 / DSD512 won't work from Lumin or any Linux-based streamer.

Re: Lumin U2 Mini
How do I set custom settings on Lumin T2. Streaming Qobuz sounds great with custom set to off but want to improve sound of my CD's that I stream through a Network Hard Drive with Lumin. Is there a specific setting for CD's? Thanks
-

Re: Lumin U2 Mini
If you're using digital output, please keep Re-sampling disabled.
You may disable any unused services such as Roon Ready, Spotify Connect, Tidal Connect, AirPlay "Lumin Streaming".Peter Lie

Re: Lumin U2 Mini
Are you looking for a de-emphasis feature? I can't think of anything else that would be "CD-specific". There is a "De-Emphasis for 44.1kHz CD Files" option under the Lumin settings.

Re: Lumin U2 Mini
If you wish to try upsampling ripped CDs then just leave everything else at 'Native' and change 44.1kHz to either 176.4kHz or DSD.
Try both and see which you prefer.
You can also change PCM Output Bit Depth to 24-bit. Again - see which you prefer.
If you like what you hear when upsampled, then you may as well change the 48Khz settings to match.[Associated with LUMIN]

Re: Lumin U2 Mini
In the first week of July 2022, there will be a firmware upgrade for U2 Mini to fix a USB low volume issue from some particular (not all) USB DAC.
If you’re using USB output from U2 Mini, there is a small chance that after doing the firmware upgrade, the DAC output volume will be increased even without changing the Lumin volume or volume control enable/disable setting.
This issue does not affect U1 / U1 Mini or any other Lumin model. They will not receive the same firmware upgrade.Peter Lie

U2 Mini comes with an internal SMPS, the same one as used in stock T2 or U1 Mini.

Re: Lumin U2 Mini
Do any Lumin models have internal storage? I looked at every model but did not find any with storage. I have a very good DAC but need a new server with internal storage.

Re: Lumin U2 Mini
None of the Lumin network players / transports have internal storage - you can stream from Tidal / Qobuz / Spotify / Roon / NAS or computer running MinimServer or L1. The Lumin L1 is a library only - it's not a streamer so you cannot connect a USB DAC to the L1.
L1 only supports its internal drive, it does NOT support addition of external USB HDD.Peter Lie

Re: Lumin U2 Mini
Good morning everyone
When I was considering the Lumin as a streamer a couple of years ago, there were complaints from users using android based tablets/phones/computers. Has this issued improved?
-
August 15, 2022, 10:17 AM #32
Re: Lumin U2 Mini
A long time ago we hired an experienced Android app developer and have rewritten the Android app since then. At this point I'd say the Android app is on par, if not better, than the iOS app. I no longer want to pick up my very old iPad Air (which has since become very slow) for Lumin app at work any more unless I have to - I just launch the Lumin app on my personal Android phone.
Lumin also offers the most flexibility for app choices - you can use other OpenHome apps like Linn Kazoo, Roon Remote app (if you use Roon), Tidal app (Tidal Connect), Spotify app (Spotify Connect), etc.Peter Lie

Re: Lumin U2 Mini
Since the beginning, when Lumin appeared on the market, I always use only android for navigating, config and updating without any problems. And the Android compatibility was the main reason I decided to buy Lumin, nor Auralic which these days was "dedicated" for Mac users (without Android app) .

Re: Lumin U2 Mini
Thanks Marcin.
Final hurdle: The Lumin OS itself.
I'm currently using a Bluesound Node with their OS. No issues, no crashes, easy to navigate.
So say its the best there is. Any ex-node users here care to comment on switching?

Re: Lumin U2 Mini
Mini 2 arrived yesterday!
Setup was a breeze. Hardest part was remembering my Tidal and Qobuz passwords.
No issues using my android tablet. Worked flawlessly.
Any way to change the background from white to dark?

Re: Lumin U2 Mini
Thanks!
Anyone use the mini as a preamp with its LEEDH digital signal processing?
Pardon me if these questions have been asked before. I'm a bit late to the party
-
August 24, 2022, 02:05 PM #43
Re: Lumin U2 Mini
I use the X1 direct to amp, using Leedh volume control. Sounds amazing to me. Have not done a true A/B with a pre-amp, but I did hear the amp at the dealer, with a pre-amp, and I don’t feel like I’ve given anything up. Could be a “real” a/b would make me feel differently, but I don’t think I’m the only one reporting that Leedh volume control works well.
When I had volume control in my previous amp, I found that using a combination of Leedh with the amp’s volume control sounded best to me. I kept the Lumin at 94, and used the amp to do the rest. Not sure why this would be the case, but it was consistent to my ear, that arrangement gave me the most of what I like.
I guess in the end, try it both ways.Main System

Re: Lumin U2 Mini
If you have a way to attenuate the volume after the Lumin then you should try both ways. Set the Lumin to 100 and adjust the volume after it... then reduce the Lumin to 99 and adjust the volume after it again. The reason this makes a difference is that LeedH processing takes places in the Lumin at all volume settings other than 100. You may decide that the processing adds something that you enjoy to the final sound.
-
August 25, 2022, 01:09 AM #45
Re: Lumin U2 Mini
Yes. There are users using it this way.
After you have familiarize with Lumin app control of it, you may A/B compare Lumin volume control against your preamp volume control (with Lumin volume control being off) to see which sounds better to you in your setup for the music you listen to. You may even try bypassing the preamp, but start playback with Lumin volume at a very low level.Peter Lie

Re: Lumin U2 Mini
Lumin U2 mini is on my purchasing radar. There are a few other contenders as well. As much as I would like to stay in the Esoteric ecosystem, stumping up $10K for a N-03T is a tough ask just for playing Spotify.

Re: Lumin U2 Mini
U2 Mini, naturally, is perfect for Esoteric DAC when it comes to Esoteric native DSD compatibility. It also has Leedh Processing Volume, FLAC radio, and some other additional features.
Note that you can use Esoteric Sound Stream app to control playback from Lumin when you're not using Spotify Connect or Tidal Connect, if you have a preference for Esoteric color scheme. Functionally you're actually staying in Esoteric ecosystem.Peter Lie
