CD has 16 Bit. And the CD-Audio-Format is everything, the human biology needs – you can’t “hear more”. So for delivery use cases its not obsolete at all, only the industry likes to sell “more” for a better price without a real benefit (and they really are succeeding with that strategy as today there are many people who believe, 96k/24Bit sounds better than CD quality — which is really not the case).
Considering that it is not our part to judge the question for 44.1k, I also cannot imagine, that such a change would or even can be done with the CQ/SQ/Dlive-Hardware.
