I’ve been assuming that my U2 Mini will send 32 bit files to the dac without changing to 24bit. I have resampling turned off and all other volume control or processing is off as well.
I am playing 32 bit DXD files with Roon. Roon says its passing the file as 32bit, and the Lumin interface also shows 32 bits (see screenshots). I am using USB output to the Holo May which shows the 384K on screen but does not show bits.
The distributor for my Holo May dac told me today that the May is a 24bit only dac and that it can’t be playing these files.
Is the Lumin downsampling the file to 24bit? Is there a way to see what the Lumin’s output is to the DAC?
I have had both 24bit and 32bit versions of the same DXD files from record companies, and doing comparisons, I hear a definite improvement with the 32bit files, they sound more like DSD than PCM, warmer, smoother, more laidback with a more subtle details.
