How can a non-oversampling DAC sound good?

[VenturaRV]

That's why there are delta-sigma DACs which allow you to reduce number of bits as sampling rate increases, because you don't need to encode vast empty silence at frequencies far in the 100+ kHz range...

 

Even without such or other fancy stuff, you gain about one bit worth of dynamic range at every doubling of sampling rate. So you could as well remove one bit out of the DAC every time you double the sampling rate.

Will you please clarify this further?

 

I'm not sure (excuse my ignorance) if you are referring to the principle that states the capability of a given channel of information by time unit is constant and the result of multiply the number of samples by the number of bits, so (because it's constant) if the number of samples increases, the number of bits decreases and viceversa. The limit will be, in both cases, a number not null of bits ( 1 ) and the highest sampling rate and, in its couterpart,

a number of samples not null ( 1 ) and the highest number of bits.

 

Am I wrong and your statement on sigma-delta converters is about a totally different thing?
