before DAC, consider sounds from your PC
plenty ventilation so case fan does not run much
audio/video from motherboard (fanless)
av card with great specs, but a fan, and how often does it's fan run?
all SD drives with no moving parts?
then, it would seem to me that the DAC world is easily full of excellent performers by this state of evolution, differences, if they can be heard (by anyone? by you?):
not 'better', but 'preferred'.
read a review, more than likely reading what the reviewer prefers.
