and perhaps where manufacturers onboard digital filters are bypassed by high software sampling rates or hardware re-samplers ?.
Some report the ES-90xx dacs benefit from being input DSD format.
The filters are in place to block ultrasonic noise. Modern delta-sigma DACs internally convert PCM into a DSD like format anyway and oversample even the max input sample rate by up to 64 times ot more. Have you never read a datasheet?
"DSD like format" ??? How does that compare to DSD ?
and "and oversample even the max input sample rate by up to 64 times ot more." seems to negate your bias against any and all oversampling ?
Google the origin of DSD or read a wikipedia article about it. DSD is literally just taking the delta-sigma output of a ADC before it's filtered and converted to PCM.
No my point is why spend the CPU cycles upsampling when the DAC does it for you in the process of the digital to analog conversion.
