Can a DAC do this or is there some DSP or analogue tweak being used to
artificially 'improve' the apparent sound stage?

Yes. Historically X-DACs have been graced with tubes. Tubes are often
used as EFX devices.

That's a point which hadn't occurred to me. :-) Yes, if the DAC uses
valves in its o/p stages then these might exhibit something like
microphony, and that could inject some amount of 'stereo reverb' picked up
from the room or the structures supporting the DAC. No idea if it would be
enough to explain the report, though.

Slainte,
