Just NO to influence depth and width you need to influence fr response and phase relationship with specific sounds in the mix not a property a DAC can have it’s not an DSP engine.
I just decodes 2 channels of audio . It’s the usual electrical waveform with amplitude on one axis and time on the other as your accustomed to with your physic teaching, it does not have more properties.
They are boringly similar
when they work properly.
So to counter that audiophile community has given you stuff like.
A renaissance for R2R DAC ( the original way of building DAC’s) , this tech can work if done properly then its gets expensive, typical delta sigma based chips DAC’s betters even the best ones for a fraction of the price .
The bad ones are not very good at all.
NOS DAC non oversampling DAC’s. A weird idea that the oversampling in DAC chips are bad ?
Filter less DAC’s the idea that digital filters are bad these does not work properly at all in reconstructing the original wave form.
These usually combines to the final horror R2R DAC with no filter
run .
If it where anything to this nonsense it would show up in the measurement of THD and noise .
Have you seen this btw.
