@grishka @c0dec0dec0de @dan I blame this on underclocked DACs in cheap equipment (96k DACs are cheaper to make than 44.1k on modern processes), as they can produce excess noise when driven outside of their design parameters. On some of these devices, a 44.1k PCM track can sound better when resampled to 96k (no longer underclooking the DAC). Better equitpment performs resampling on the fly instead of underclocking.

The real test of hearing is whether that original 96k rip sounds different when converted to 44.1k and then converted back.

@gtsteel @grishka @dan that an ongoing problem or is that like someone being afraid to hotplug USB because historical serial peripherals were not universally safe to hotplug (like might fry a board unsafe)?

@c0dec0dec0de @grishka @dan It's an ongoing problem in cheap gear, as manufacturers will always find ways to cut corners. This is also the reason why the opus tests were done as opus vs resampled to 48k (opus's output rate) instead of opus vs 44.1k original.

It's not such a problem in higher-end gear though, as good manufacturers have fngured out the combination of resampling in a DSP and a 96k (or more) DAC works quite well and is still quite a bit cheaper than a native 44.1k DAC (which requires a more precice and complex analog filter). Some of them even digitally convert to DSD and directly drive a switching amp (which makes the analog side even simpler).
