Vivaldi upsampler's future

I dug a bit deeper and pulled the following from here

@James

Moving to a hi-res format like 24-bit, this dynamic range increases to 144dB – assuming the equipment is actually capable of working in true 24-bit.

It is a common misconception that 24-bit audio simply records louder and quieter sounds than is possible with 16-bit audio, but this is not the case. Instead, the same range of loudest to quietest is measured, but with 24-bit sampling it is done with considerably more steps than with 16-bit. This means the absolute value of the waveform at any given point can be much better represented.

When working with hi-res audio, each additional bit which is added to the bit-depth of a signal halves the quantisation error, quarters the error power, and thus reduces quantisation noise by 6dB.

That doesn’t give us the answer to the question whether Vivaldi Upsampler does any processing beyond adding zeroes in order to get from 16 to 24 bit depth. It tells us however there is value in upsampling/processing the bit depth beyond adding zeroes.
