  1. If the album count is not changed after MinimServer Rescan, the Lumin app Update Music Library needs to be invoked manually.
  2. After issuing MinimServer Rescan (from Lumin app or MinimWatch), please wait for the operation to finish. Normally Lumin app should update automatically after that was completed after a certain amount of time and found a different album count. If for some reason it does not, you may double tap iPad home button, swipe away Lumin app and relaunch it. If you're sure the rescan has already been completed and after relaunch Lumin app still does not get the update, then you can do the Update Music Library (which should not be necessary). The Lumin app Reload Music Library is normally not used, unless you want to delete the local Lumin app cached database and rebuild the database from scratch. This takes a long time if the library is large.
  3. You may set analog output level to low and disable digital audio output. See if this gives you enough range with the preamp volume. If that's not enough, please reset analog output level back to normal, then do a volume-matched A/B comparison of XLR and RCA outputs (not simultaneously connected) at your typical listening volume, i.e. between option 1 and 2 first. You may use a smartphone with a sound meter app at your listening position. If RCA sounds better to you, then stick with RCA. If XLR sounds better to you, then proceed to try balanced attenuators.
  4. Spotify Connect for Lumin is delivered in 320kbps ogg of 16/44.1. It is not upsampled unless you changed the custom re-sampling settings.
  5. It is Lumin proprietary. iOS upgrade should not modify the Lumin playlists otherwise it will break Lumin app.
  6. We never tried that, but I guess any regular programmer's editor that retains UNIX/DOS newline format should work.
  7. @tranzPlease go into router settings, find the DHCP server function, and reserve an IP address for the NAS running MinimServer (or any other UPnP music server for the library), and an IP address for the Lumin (in case you use directly connected USB storage for music).
  8. Lumin players keep the current playlist in its internal (tiny) storage, not a hard drive. Other saved playlists are kept by Lumin app on iOS device. If you enable iCloud for Lumin app, then the saved playlists are synced across multiple iOS devices and should survive re-installation of Lumin app. This is true for L1, MinimServer or any other general UPnP music server.
  9. I'm just not sure whether MinimStreamer converts DSD256 to PCM. I know it does for DSD64 and DSD128.
  10. @Fife Yes. All Lumin products (except M1 integrated amplifier) allow you to disable the volume control.
  11. This would be my own preference, not anything objectively better, and assuming you want to avoid re-ripping in the future: If you are using Roon, and you're going to upgrade in the foreseeable future, then DSD256. Roon can downsample the music on the fly for playback before you upgrade to something that plays DSD256. If you are not using Roon and have no plan to upgrade, between 352/176kHz and 384/192kHz I would choose 352 or 176kHz. The reasons are that if you want to try DSD upsampling with software, 352/176kHz works better than 384/192kHz because 352800Hz x 64 = 22.5792MHz i.e. DSD512. I've seen another non-Lumin audiophile brand that has a better clock for 44.1kHz-multiple family of music than for 48kHz-multiple family of music, so the former in theory plays better on its DAC architecture. If you really have no plan to upgrade anytime soon, I suggest you experiment with DSD64, PCM 176.4kHz, PCM 192kHz and see which sounds better to you with the Lumin A1.
  12. Previously Lumin DSD256 and DSD512 USB output worked on modern models of XMOS-based DAC and Esoteric / TEAC DAC but not Amanero-based DAC such as most models of LampizatOr. There are now experimental firmware upgrades for both LampizatOr / Amanero-based DSD DAC and Lumin U1 / U1 MINI / T2 / X1 to enable Lumin to send DSD512 (not for U1 MINI) or DSD256 to DAC via USB. There are risks involved in DAC firmware upgrade procedure and the use of experimental firmware, so proceed with caution. If you're running an Amanero USB firmware older than 2002BE on your LampizatOr, you need to ask LampizatOr for upgrade instruction suitable for your particular DAC model. If you're using a non-LampizatOr DAC that uses Amanero USB board, please consult your DAC manufacturer. Important: 1. Take note of which firmware version you are currently running before proceeding to upgrade to a new firmware. 2. Some DAC need DSD channel swap firmware, some don't. Getting this wrong will result in DSD left/right channel being reversed. After upgrading LampizatOr / Amanero, please test playback of different tracks of PCM and DSD64 / DSD128 to be working with no new and unexpected issue (e.g. pop / noise / left right channel swap / mute issues) with track changes. Then you may get an experimental firmware from me to upgrade the Lumin U1 / U1 MINI / T2 / X1. If everything works as expected you can then play DSD256 music files, or upsample to DSD512 / DSD256 via Roon. In case there is anyone using a current model of Mytek (e.g. Brooklyn DAC+) or a modern XMOS-based DAC but Lumin USB output of DSD256 does not work, this firmware may also fix it.
  13. Yes, you can simply plug in a USB storage device to a Lumin. For a larger library running the freeware MinimServer on a computer or NAS is preferred, as it offers better browsing speed and more artist / album views. Lumin app is available on Android but the iOS version is more mature. Lumin is OpenHome compliant so it's also possible to use other Android apps including Linn Kazoo and Bubble DS Next to control a Lumin player.
  14. Since Lumin is mentioned I'd like to provide some info on whether internet is required. Internet is not required if internet firmware upgrade, Tidal, Qobuz, and TuneIn internet radio features are not to be used. However, a local WiFi network is always required. A Lumin setup requires a WiFi router. The iPad (running Lumin app) connects to its WiFi. The Lumin connects to the router via a network cable. Lumin does not currently support Bluetooth.
  15. Lumin does not currently support HQ Player NAA. It supports Roon upsampling over RAAT.
