You could logout Tidal from Lumin app, then try the free Linn Kazoo app.  There are other OpenHome / UPnP control points you may use with Lumin, even including JRiver or Audirvana.

 

The best and most stable app for Lumin is by my experience "BubbleDS". I am not able to use Tidal in the Linn Kazoo app, nothing comes to the screen when logged in to Tidal.

If you enable Leedh Processing Volume and Volume Control, it is always applied if volume is below 100.

 

For Lumin X1 T2 analog output, the Lumin proprietary implementation of Leedh Processing Volume is always perfectly lossless - no bit is lost within the CPU processing for both PCM and DSD signals.

 

For digital output, please refer to the information on Leedh web site.

Thank you Peter for setting the record straight at least for the analog outputs of the X1.

Thank you for clarifying, Peter.  That's wonderful.

To access Tidal you need to go back to the server screen ...and its there. Ive been using the Linn music app. It’s only on iOS at the moment but very good...except for deleting play queues...a bit long winded.

No, it’s on IOS. Do you remember how you disabled it? I cannot find anywhere to do that.

I’m afraid I can’t exactly recall how I got rid of the pop up screen.
 

Maybe you first have to have i.e. Minimserver running and choose a library. Then remove it. (Musiclibrary> Options> Remove music library, and it no longer automatically asks for it.

Thanks. I have also had some issues with Linn apps. Is this an Android app? I was not able to find it on IOS, just loads and loads of bubble games...

what point on the Lumin Leedh volume scale of 1-100 does -30dB represent?

 

For most Lumin models (M1 excluded), each volume step decrease from 100 is -0.5dB.

 

So volume 40 is -30dB, if Max Volume % is 100%.

1. And for the older T1, A1, S1 models, are they always lossless too when Leedh is used between 0 and 99 volume?

 

2. Also, switching the output to 'Low' in the app... I understand from a previous post of yours, that this reduces the peak to peak output level from 6v to 2v. Does this apply to ALL models in the Lumin range?

 

Thank you.

[wklie]

1. Yes for S1 analog output.

 

2. 6V / 2V are for X1 T2 (and probably future models) only.

 

Older models S1 A1 T1 D1 D2 output 4V rms for XLR.

 That is such useful information Peter. Thank you.

Is there any big difference for using Lumin U1 mini vs MacBook Pro?

[ZombieMelvile]

Hi All, first post here, Just received my Lumin u1 mini and hooked it up.I have few question if you could help would be great

-should lumin Volume control be on or off , and if on then what level should it be , I currenly have it on at 90!

-Lumin screen reads "Mute" ,also the app shows the same on the upper right corner of the app screen , this doesn't change if I press on it.

-I understand that Leedh processing volume will be something to try for a bit to see what difference dose it make , is that what everyone doing or should I leave it on 

-I stream mainly from Roon which works fine, but I tried streaming from my iPhone 12pro using Tidal and Qobuz but I don't see Lumin Mini unless I play via airplay , is there a way that Lumin App will play Tidal and Qoubz from within the app itself?

Apologies for all that newbie questions

[ZombieMelvile]

apologies, Newbie alright, Installed the App and reinstalled it and it works fine now

really enjoying the music more now with the Lumin mini

Of those user feedback sent to me about migrating from a Mac source to U1 (MINI), 100% of them reported a positive improvement.

 

In addition, you cannot get native DSD256 from a Mac (unless your DAC supports DSD256 DoP or provides a special Mac OS driver).

Please start with Volume Control OFF.  Only after you're familiar with the operation and are prepared to do A/B comparison against another volume control in your playback chain should you turn it on.

 

If the app does not correctly show the behavior of U1 MINI, please double tap iOS home button, swipe away the Lumin app and relaunch it.

 

Tidal Qobuz are accessed from within Lumin app, not via Tidal app or Qobuz app.  Spotify is only accessible with Spotify app.

Thanks.

is the clock in lumin U1 mini is Oxco ?

Is the usb output using the clock ?

[wklie]

It is a low phase noise oscillator.

Thanks,

is the usb is using the oscillator , should I add uptone iso regen ?

[wklie]

We actually have multiple low phase noise oscillators on it, and the CPU USB uses one of them.

 

Whether you choose to use further USB cleaning product is up to you.  Some users tried it and it should be compatible.

In my view it is. Of course one can always debate what "big" means.

 

In my view the biggest advantage is that you get rid of using the usb card from your laptop. Instead you go with TP ethernet connection from your source in the same way as done from Roon, Tidal, Quboz all the way to the server which then is optimized for transfer music streams to your dac using different connection options including USB, AES/EBU, Coax. Whatever the Lumin does they do it better than a laptop. I guess it has to do with clocking, low noise oscilating. I find the sound to be more relaxed, clean and full bodies vs playing from a laptop. Personally I prefer AES/EBU that takes up to 24/192. When I play DSD I convert it to the same format or switch to an USB cable. Unfortunately you can't have both connected at the same time. A switch in order arrange this should be perfect. I have also tried Tidal and it works excellent which I know Quboz and Roon do as well.

 

Lumin is optimized for sound and it is a process on-going with automatic system upgrades. A laptop is a compromize for "everything". The app works excellent with no delays and the most important search criterias to sort and find your music files (if you manage your files accordingly). The only drawback is that you need an OS plattform. Android does not work (I have tried on two Samsung Galaxies, Samsung and Sony Phones. It turns off and restart all time. You are asked to give feedback but no improvements to be seen. 

 

I run my Lumin with music files from my own downloads and ripped files that are stored on a Synology NAS with Minimserver 2 (free) software. Downloads, ripping and files are handled in my laptop on the network using Mp3Tag and then exported to the NAS storage. From the NAS I have a 20 meters ethernet CAT6 cable going to English Electric switch and from there an earthed RJ45 cable (Chord Epic).

 

I'm very happy with the solution. My digital music listening has been put in another league than before.

[Mat]

Thanks Ropet

Regarding Samsung Galaxy, our latest Android app changed something to fix the start up crash on Note 10, although the same crash did not occur on S10.  There are Android OS-level inconsistencies even within the same brand.

Thanks Peter that is great advice ,will adjust things now

I have been using the Lumin app to control a non-Lumin streamer along with minimserver 2. Some of my albums contain the Group tag to "group" individual movements of a work such as the movements of a symphony. In the Lumin app any piece that contains the Group tag is separated from the album and sorted by the Group tag rather than being part of the album. In other words, any tracks on the album that contain a Group tag are sorted by the Group tag instead of remaining as part of the album. Tracks without the Group tag remain sorted by the album name. Is this intended behavior or am I doing something incorrectly?
