"Of course digital can not generate this "treble air"."
Sure it can. Try upsampling.
My Zero One Mercury CD/HD player has selectable oversampling and upsampling from 44kHz to 196KHz. I find that the oversampling modes (even multiples of 44KHz such as 176KHz) sound much cleaner and more natural then the upsampling modes (such as 196KHz), which tend to introduce the "treble air" you speak of. At first it sounds like an enhancement, but soon it starts grating on my nerves.
I can also select the high-frequency filter to be the typical brickwall or several more gentle slopes; I find the HQ2 setting the best (between brickwall and very shallow slope) - too shallow a slope and you get unwanted high-frequency stuff introduced to the components that makes it sound markedly worse, too steep and you get noticable ringing on HF notes.
Finally, I can also choose the dither setting used to reduce noise - in this case I prefer no dither at all.
