I assumed the OP is interested to know whether listening to the playback in QuickLook is going to be a valid exercise
for a pro audio person, versus opening the file in any particular application.
It could certainly be a less onerous workflow for one to quickly review audio and choose a good take or a good mix.
If QuickLook were coloring the audio differently than other software that would be a workflow to avoid.
(and something to note to a customer!)
Probably worth filing a radar or checking on the core audio list.
