Just a question about the Pro 9028 OSF filter. The OSF can be switched off with SW2:2, in which case you need to supply your own OSF. I'm using HQPlayer to oversample everything to DSD512 using HQPlayer's own filters, so I guess I can shut off the DAC's internal OSF and just go with the HQPlayer filter.
However, the ES9028 datasheet states that the "FIR filter is bypassed" when playing DSD...does that mean the DAC is already automatically disabling its OSF whenever DSD is played? If so there would be no need to switch off the DAC's OSF manually.
A clarification on this would be greatly appreciated!

I keep mine turned off all the time. But I believe your understanding is correct. You could leave the OSF active for I2S and it would be automatically disabled for any DSD input.
