Roon DSP headroom management and volume leveling
I don't sweat intersample overs. Roon handles it. If they happen, I never hear their effect.
From the Roon website:
Because of "inter-sample overs"
"It's possible for a totally "in-range" piece of source material to have "out-of-range" samples after upsampling. The very simple explanation is: when the interpolator "connects the dots" to form a signal at a higher sampling rate, sometimes the new "dots" fall out of range - causing clipping.
This is essentially a defect introduced in the mastering process and is not a problem with the upsampler. Unfortunately, most software silently ignores these defects and provides no means to track or manage them. "
Some DACs from Benchmark and others are able to properly handle intersample overs through DSP done within the DAC but separate from the DAC chip itself.
