I'd vote for it being digitally generated aliasing - all too common a mistake.

Granted, you have to record higher than 44.1 kHz to see this, since most DAC hardware is running at least that sample rate or higher.

How can you tell that's down to poor reconstruction filtering, as opposed to generated aliasing from the numerical side?
