Lumin T2 burn in time?

A lot of people on other audiophile sites such as AudioShark claim they think it provides for an even better sound. By using Leedh, You put your preamp in unity gain and control the volume using the Lumin app.  By doing this, it basically takes the preamp out if the chain.  Many claim it sounds like a veil has been lifted and is even more clear.  I have tried it but not sure if I can tell a difference.

Hi xcool.I’m from LUMIN and I just wanted to add a little info.

Firstly LUMIN is manufactured by Pixel Magic Systems and is totally independent of any other company. The LUMIN App is our creation. Esoteric, TEAC and others licence the App from us to use with their streaming products.

iOS is our primary development platform. It is very stable on iPhone and iPad.
If instability exists, please try a restore - this cleanly installs all apps and can resolve some issues. The only performance requirement is regarding cache. LUMIN App is unique in it’s local storage of album artwork - for large libraries with high resolution artwork, this can require quite a bit of storage - most devices have large storage these days, but our App works back to older devices too (when storage might only be 16GB), so it’s worth bearing in mind.

Android is trickier, as there are far more variations between vendors and Android implementations. Testing is much harder, but we believe we have now reached a level of stability that should provide trouble-free playback for most. Again, the app is quite sophisticated in it’s interactions with the device, so clean systems are beneficial.

Because we use the OpenHome standard (UPnP AV) for streaming, for people who don’t get along with our app for playback you can also use other UPnP apps such as Kazoo, BubbleUPnP and others. Some are free.
LUMIN App is required for changing system settings and for firmware upgrades, but playback can be achieved with any of these apps.

Regarding burn-in. We get a broad spread of customer opinions on this, but we seem to have settled on advising about a week of 24/7 playing using a playlist on repeat containing a variety of music resolutions before critical analysis. Your amplifier doesn’t need to be on during this time, so it can be done silently overnight.
We have reports of improvements after even longer than that, but certainly the first couple of hundred hours is worthwhile.

Hope that helps.

thingswelike,
I have just sent you a PM. Please respond.

What settings are you using? I have a D2 and also going through a preamp, mine are:
Volume Control: Off
Analog Audio Output Level: Low
De-Emphasis for 44.1kHz CD Files: Off
Digital Audio Output: Off
MQA Mode: Analog Output
Ultra-sonic Filter for DSD Playback: Off
Re-Sampling: Off

Just in case one of these is the culprit. I realize it’s not the same as the T2, but bass has been quite good for me. I really haven’t tried toggling these other than setting the output to low gain and turning off volume control otherwise the gain through my preamp cranked the volume to insane levels, as it is I don’t go above 1/3 otherwise neighbors get super grumpy. Anyway hoping it’s just a toggle setting. Oh my use case is 99% stream tidal hifi/master.

Hi @thingswelike thanks for the lengthy reply.   I'll try to take a look at your suggestion.

BTW, I have another comment about the Lumin App.   It's about the implementation of the "shuffle/random" feature of the playlist.

First of all, when the shuffle feature is turned on, the current playlist is still displayed in the original insertion order, and I noticed that some songs can possible be selected more than once before the playlist is finished.   Also, you have no idea what the next song will be ahead of time.   It seems to me that the shuffle implementation picks the next song randomly when the current song is finished, therefore it is possible that a song can be played more than once.  Am I correct with my observation?

I'm comparing your implementation against something like the Cambridge Audio app.  In the Cambridge implementation, when shuffle feature is turned on, the current playlist gets randomized and displayed in this new randomized order.  You know exactly what the next song will be, and also the same song will not be played more than once before all the songs in the playlist have been played.

Your comment on this will be appreciated.  Thanks.
