LUMIN - Audiophile Network Music Player

[eis]

I was prompted to update my D2 firmware yesterday and now it will not boot up beyond the Lumin logo on screen. It is not seen in the app. Was working great prior to that.

 

I have disconnected all the cables and rebooted my router. Left if off for over 30 minutes. Powered back up, no change. Never goes to the circle.

[eis]

Just tried the factory reset... Still the same.

@eis Please check PM.

In case anyone hears a SQ difference after upgrading from firmware 13.x to 14.0, please report and state your model.

I know it is recommended NOT to use both the RCA outputs at the same time as using the XLR outputs.  But is it ok to use a Luminous device with both sets of outputs connected to 2 other devices, if only one of those devices is powered up and used at a time? Or will there still be a deterioration in sound? It’s so that I don’t have to keep reaching round behind all of my gear all the time. Advice would be gratefully received!

[wklie]

Firmware 14 actually also has the following important changes not listed in the web release notes, applicable to all models:

- Improve network bandwidth usage for gapless playback

- Improve processing efficiency

These could impact SQ, however small the difference is.

Sorry, my iPhone auto spellchecker messed up my post (above) a few times!

For X1 / S1 / A1 / T1, simultaneous connection of XLR and RCA will degrade the SQ.  That being said, if you're not having a ground loop and you don't notice much of a difference without a serious A/B comparison, then don't worry about it.

I noticed that the starting of TIDAL playback is much slower now. For all tracks

[wklie]

Which Lumin model?

[wklie]

I found that you are using T1.

 

In Lumin app About of Lumin T1, please check that DNS Server is 8.8.8.8 and your Firmware is 14.0.

In Lumin app, please enter #DNS in uppercase in the Lumin name field (only works on Firmware 14 or later).  Wait for 60 seconds, then power cycle the T1.

Upon reboot, please check the About screen and verify that the DNS Server is different.  Then retry Tidal playback.

Hi Peter @wklieafter the upgrade to 14.0a I have noticed the sound is a little bit of warmer more soft. I use lumin u1 mini

Thanks for the information.  And for the transparency.  I, for one, have noticed no change to SQ I can attribute to the firmware update.

For your sonic preference, is this good or not good?

[nikolaos1969]

 I like the difference in the sound because it has not lost its transparency

[Sanjeev]

I also noticed sonic difference after updating to 14.0a and it is on better side. I am using X1.

I don't hear any difference.

 

But I remember when I owned my PS Audio DirectStream DAC, whenever they would release a new firmware, there would be all of these accolades about "greater air" and "more refined", etc. I never heard any differences.

 

Not to say that there aren't any, I just don't hear them. (I only critically listen to classical music ).

My point exactly.  Tell someone there is a change that might affect SQ and even a deaf person will be able to discern it.  No disrespect to deaf people either expressed or implied.

[wklie]

Yes, I'm well aware that simply mentioning it and asking about it causes expectation bias.  But then if I don't ask, some of those who do hear a tiny little difference may not post about it proactively.  To prove that it goes both ways, one user reported it sounded worse (faster pace that sounded odd).

 

I need those feedback because I need to know whether the changes I made caused an audible SQ difference or not, and whether the changes are done in the right direction.

[BlueSkyy]

For me, your honesty and forthrightness is a blessing and it can be a curse.  Continue doing what you do because you guys do it so VERY well!

[samatman]

Hi,

After the update, using AES output from U1 mini to Matrix x-sabre pro mqa DAC, there is no MQA information. Only by using USB output. This wasn't the case before the update. Am I doing something wrong?

[SQFIRST]

Brand new user here so please excuse any mistakes.

I created an account simply to provide feedback to Peter at Lumin as I am a Lumin X1 user.

 

Firmware v14 is a definite improvement in my case. Previously, I used to find a slight edge in using Roonserver because I can fine tune the sound using its Convolution filter. I do not upsample or use any other filters and prefer to listen to a stream in original format. In my setup using the optimized Roon server provided slightly better transparency over the Lumin App. After the v14 update, things are very close without the Roonserver. Using Tidal connect via Tidal App sounds really good. Lumin App now sounds really good. All in all, I will vote a huge thumbs up to the changes.

No major differences, the important checks for soundstage,  height are where they should be, maybe position of sounds are a bit more focussed. This tells me there's nothing different in timing and software hasn't screwed this up.

 

 If the soundstage collapsed, then small details vanish and there are differences tonally since the complete event is missing the foundations. Version 14a uploaded, Lumin app for play back. U1 model.

Minimserver versus Jriver as DLNA server

 

If I download an album, I would want to listen to it *now*. Minimserver needs a restart, cause I'm impatient, and have to wait to sift through 8192 albums cataloging..... Also the Lumin app has to update as well? While I work through this dilemma, thought bubble to change to why not try Jriver as DLNA server, since Jriver is used on the office PC, the library and settings are already setup, won't take long to trial.

 

The renaming of the library location from a network drive to a local one, couldn't happen. A message opened "Some files could not be renamed". No reason as to why or which files couldn't be renamed, just didn't happen. FU. Overnight made a new library from local files, this morning played 1/10th of ONE track. Ugh. Worse than Roon, just mush, poor soundstage, tonally very bad.

 

If you're thinking about Jriver Media Center as DLNA server - Forget it.

My experience with JRiver MC tells me your issue lies elsewhere.  My A1, S1, and X1 have all sounded marvelous regardless of how the files get to the Lumin.
