There is an anomaly of file handling between the Lumin U1 Mini and my DAC

Proof that Lumin USB outputs 32 bit from Roon using RME ADI-2 Pro FS DAC native bit test:

Lumin USB 32-bit output was tested OK with some DAC based on XMOS USB chip and ITF USB chip. In case of the DAC using ITF USB chip, a corporate customer tested it for us.

DAC-specific issue cannot be investigated without a DAC being accessible by us. Besides, if 24-bit works, then it’s not a great problem as 32-bit is not offering any gains at the DAC. (32-bit is only useful as an intermediate step in signal processing.) According to Stereophile measurements, no existing DAC has higher than measured 22 bit resolution.

I dont really care and nobody should care with some test you did with some unknown DAC
I want Lumin U1 Mini to send 32 bits flow to my Sony TA-H1ES 32 bits DAC
It is stated in your webpage that it is a 32 bits player
So why it is not working with my 32 bits DAC? This is outrageous
That means that what you state in your Lumin products specs may not work with all the related setups
This is a big thing one should have in mind!
