  1. On iPhone and iPad, after enabling lossless in settings, and use the built-in iOS device speaker to play, we can see Lossless logo in the list of tracks for an album. My question is, when you bring up the playing screen where you see a larger album art, and only the current playing track name is shown (instead of a list of tracks), do you see the Lossless logo? I cannot for most of the albums I tried (over a dozen, including Taylor Swift). I suspect this is a regional thing, or perhaps I did something wrong. Thanks.
  2. If possible, please try the iOS system panel AirPlay (instead of in-app AirPlay) and see if it makes any difference
  3. Branding lossy as Premium does not make much sense to me either. From time to time there were users who subscribed to the wrong tier because of this misleading word.
  4. Hypothetically even if it is upgraded (I'm not saying it's possible), you cannot get Apple Music Hi-Res delivery over AirPlay.
  5. 24/48 is lossless (not Hi-Res) by Apple definition. 24/48 (or anything above 16/44.1) is Hi-Res by Qobuz definition, and is generally accepted in the audio community (I believe).
  6. Current Lumin AirPlay implementation is restricted to ALAC 44.1kHz.
  7. What Apple device are you using? iPhone / iPad, Mac, Apple TV? If you using a Mac, you need to use the system AirPlay, not the app AirPlay.
  8. My speculation is that in this scenario you're getting an AAC stream from the service, then it gets converted to ALAC and is sent to Lumin. Perhaps watching a network traffic monitor may prove or disprove this speculation. So it's best to choose the system wide AirPlay instead, such that the app shows it's lossless. In this usage, please set the Mac to 44.1kHz since Lumin AirPlay is currently fixed at 44.1kHz.
  9. For stereo tracks, at this time you get the best (neither claiming nor denying it is lossless delivery) results from having a USB DAC connected to an iOS device (via an appropriate adapter) but not a Mac.
  10. Current firmware for all models of Lumin network streamers only supports ALAC and does not accept AAC in the current implementation of AirPlay 1.
  11. The protocol can be lossless ALAC 44.1kHz, but it still depends on the apps and the OS to do everything in a manner that avoids harming bit perfect transmission.
  12. In a certain Facebook audio group there is a discussion about whether short fiber can be safely used. My answer is that with 10km SFP modules, there is negligible concern of damage, according to P.77 and P.78 "Damage by Overpowered Transmitters?" of https://archive.nanog.org/meetings/nanog57/presentations/Monday/mon.tutorial.Steenbergen.Optical.39.pdf All the SFP modules in use by Lumin office have continued to work. Hypothetically, even if it dies after being used for several years in a consumer audio setup, we are talking SFP modules which cost only $7 - $50.
  13. @PJ4301Your app update did not solve the problem because the app merely allowed you to browse and add Tidal tracks to the network module (renderer). The app does not actually do the decoding in a normal UPnP architecture. The decoding is done in the network module for your hardware.
  14. @ecwl I guess skipping should be a different problem from the tag-dependent behavior discussed above. Please test playback of local MQA files downloaded from 2L website above, which should work. Then remove the tags, and retry. See if this: 1. Play or skip 2. If it plays, whether MQA indicator is shown
