There is a sound quality related change that we're experimenting on for Lumin T2 and X1.

I need users to tell me whether it sounds the same, better, or worse.

If you use a Lumin T2 or X1 analog output and are interested in participating in this test, please let me know and state your model you're using.

If you happen to be using a preamp that supports AV bypass feature, or using a direct-to-amp setup (i.e. using Lumin volume), please also let me know.
 

 

An added benefit of participating in the test is that I've decided to permanently bypass my AV processor when listening critically to the Lumin X1 and, rather, pump the XLR outputs of the X1 through a high quality (expensive?) XLR switch box directly into the front end of the L/R front mono amplifiers.  Because the X1's output is such that the volume control is running about 10 at normal listening levels, I will probably have to set the X1's analog output levels to the lower setting or install a couple of balanced attenuators in the X1's output going to the switch.

 

A question for the designers: Effectively, when going to the low analog output setting, how is the output being reduced and would you think there is any possibility for "harming" the sonic quality of the output by using the low setting?

This looks like a minimserver issue to my eyes. My advice to you is to contact https://forum.minimserver.com/

 

I'm sure you will get a fast reply and accurate solutions. Their service is top notch. 

@Berlin -- you also need to install minimwatch. Minimwatch is the tool to do detailed configuration of minimserver.

The how part is proprietary.  Normal is the ideal setting.

 

Alternatively, the RCA output is lower by half, if your mono amps support unbalanced input.

Understood.  Since I am locked into using the balanced connections, I will go the passive attenuator route for the time being.

@Berlin

I agree. This is true if you run a NAS and use a pc/laptop to configurate the NAS. But if you use a pc/laptop as the server with an external HDD, you do not need Minimwatch. Then you do the configuration direct in Minimserver (this is my setup using a dedicated laptop only for this and for downloads).

 

You also need a database of course. I use Mp3Tag.de which also have a number of possibilities to arrange your data. They have also excellent service over the web.

@Berlin if you are on macOS you could try Yate, I’m using it, (2manyrobots.com) or https://www.dbpoweramp.com/

Following some user enquiries about Spotify Lumin issue, I integrated the Spotify March 2020 SDK, and found reports of worldwide outage.

 

Intensively testing Spotify Connect in the last few days, I ran into a situation where Spotify plays on iPad but not on Lumin. Did the followings to no avail:

- Made sure I'm running latest Spotify app
- Rolled back my experimental changes
- Power cycled Lumin
- Tried different Spotify SDK
- Tried different versions of Lumin firmware
- Killed and restarted Spotify app

- Waited for another day to retest

Tried an Android device - that works! So I did the followings, again to no avail:
- Rebooted iPad
- Switched to a different WiFi SSID

Ultimately, what solved my Lumin Spotify problem is to logout from Spotify app, then relogin.  Now Spotify can play to my Lumin setup.

But the story does not end here.

I set Spotify back to play on iPad, but there is no sound from the iPad.  Switching back to Lumin, Lumin Spotify Connect playback is ok.  Switch back to iPad, still no sound. Killed the Spotify app again and restarted it, still no good.  I asked my marketing manager for help.  He examined the volume status after double tap home, and tried some volume changes.  Then he started YouTube app, which works of course.  Back to Spotify, now it produces sound.

Is there any way to prevent the Settings/Music Library window from popping open every time I go back into the Lumin app after X minutes? I don’t know what X minutes are but I’d prefer it not open at all. 
 

 

[wklie]

Please make sure you have chosen a library (i.e. MinimServer).

I don’t use a local library. I only stream Qobuz / Tidal

This is my wish also. The app now and then reverts to the library, whether it exists or not. Would be nice to always stay at the last chosen “source” like Qobuz.

We just received this e-mail from a happy customer:

I just have to let you guys know - I have used my LUMIN D1 for 5 years and was happy. Four months ago I sold my D1 and upgraded to the LUMIN T2. I noticed an improvement in all aspects of my system (Krell 300i pushing Maggie 1.7i speakers) - sound stage, depth, bass, vocals, cymbals, etc. I was very happy. No one told me there was a ‘break in period’!! This system sounds better than I ever imagined four months in!

Thank you for an ‘Over the Moon’ quality product!! I just had to let you know!

A very happy customer for life!

Is it possible to make in the application, "repeat point a-b", as in many cd players.

[Kray]

@wklie can you take our suggestion above into consideration as a feature request? If I don’t have a local music library and only stream Qobuz/Tidal, I shouldn’t have to be forced into the blank Music Library menu all the time.

Yes please, it is rather annoying 😉

I have talked to our team about this.

Peter,

 

Any plans to add HQ Player NAA functionality to Lumin T2.  Love the product, but miss the ability to use HQ Player, as I am able to with the ultrarendu.

[steveoat]

Peter:

 

One other request.  Could you please add Amazon Music HD to the streaming services you support.  The Bluesound integration is terrible.  I hear that the Marantz/Denon Heos is OK, but would love to have this on my Lumin streamer.

Please AirPlay from Amazon music on iPad to Lumin.

[steveoat]

But doesn't only Airplay 2 do Hi Resolution?  I thought regular airplay gives redbook only.  We need something for high resolution

AirPlay 2 doesn't do high resolution either.

The issue with Amazon Music HD isn't with the HiFi companies. It's with Amazon being nearly impossible to work with as a company. I know many HiFi companies who would implement Amazon Music HD instantly, if Amazon was anything like Tidal and Qobuz.

[steveoat]

So airplay isn't an acceptable solution for Amazon Music HD.  We need something custom

Given some news media suggestion of possible change of US tariff for Hong Kong (where I work), I encourage US customers who are considering to purchase a Lumin to place your order ASAP.
