If the 24/48 is actually MQA, then why if the same file/track had been run from the Tidal desktop application directly to a DAC that is at least 24/96 capable and would play at 24/48 or 24/96 on the DAC, why will it only show up and play as 24/48 on the DAC if played via the Lumin as you describe?......thx
Tidal desktop app has the ability to perform a software decode of MQA from 24/48 to become 24/96 and feed it to a directly connected USB DAC, if the desktop app is set to Exclusive mode and MQA Passthrough is unchecked.
In a Lumin setup, Lumin player is controlled by Lumin app on iPad. It plays Tidal natively without requiring the presence of a computer or any Tidal app. Lumin does not have the ability to decode MQA yet. This capability is being considered.
