Maybe I did not express myself properly
I have many DSD recordings, DSD64 (most), DSD128 and DSD256. JRiver sends Bitstream as DSD but only DSD64 is playable. There is silence when attempting to play the others. I did raise this question in a previous post and was informed that DSD64 was the upper limit of Bitstream
If these higher resolution Bitstream is converted to 24 bit 176KHz then there is no problem
Many Channel Classics recordings are in DSD 128, likewise some remastered older recordings
The comment below still does not explain why higher resolution DSD recordings will not play...
I came across this from a Firmware manual:
MAT DSD Core technology converts the DSD format into Expert internal native PCM 40 bits / 384 kHz format thanks to an optimized algorithm, limiting the amount of computational operations on the audio stream. Using only 15 bit perfect additions (no multiplication, no storage), the MAT algorithm performs a 128 taps, linear phase FIR (Finite Impulse Response) digital filter ensuring the conversion of the DSD format into internal native PCM format with truly outstanding performances
