Firmware 20 adds support for Amazon Music Unlimited and QRONO d2a - both require the latest Lumin app 12 for iOS, or app 9 for Android.

Amazon Music Unlimited is available for Lumin P1MINI T3X T3 D3 U2-series.

QRONO d2a provides a MQA-style sound signature for non-MQA PCM music. QRONO d2a is optionally enabled, available for Lumin X1 P1 P1MINI T3X T3 T2 when using analog output.

Several years ago, when people tried to compare the sound between a non-MQA album and the corresponding MQA album, there was always a question of whether both came from the same master, which is impossible to know. In specific cases, there was a criticism of differing loudness. Now Lumin QRONO d2a is optionally enabled, so users can listen to the same PCM track in Lumin default linear phase filter vs QRONO d2a, to see which sounds better.

For those who are interested in carrying out this test, I suggest using 44.1kHz PCM. Please let me know your preferences.

In Lumin app settings of MQA Mode:
  • QRONO d2a: enables MQA Full Decoding for MQA music and QRONO d2a for PCM music
  • Full Decoder: enables MQA Full Decoding for MQA music and Lumin linear phase filter for PCM music
QRONO d2a is only supported for playback using Roon, Lumin app play queue, and Tidal Connect.
 
I find the opportunity to try QRONO d2a an interesting development. (I was not one of the anti-MQA folks.) I'd be interested in hearing the experiences of others who have tried this. I'm still at firmare 18.1 on my P1, and am always reluctant to update. :)
 
What is the reason Amazon Music Unlimited is not supported on the U1-series (in my case U1 mini)? Is it a hardware limitation (seems unlikely), or is an update forthcoming, or are these type of enhancements no longer available for the U1 series moving forward?

Thanks,
Tom
