5. Re: High Sample Rates

<<because higher sample rates mean less quantization noise - at least

Actually the quantizing noise is a function of bit depth rather than
sample rate. This is why 24bit is preferred over 16bit, but again "at
least in theory", since no analog electronics will ever be able to
portray the full dynamic range inherent in a 24bit data stream. It is
also possible for a high sample rate to measure worse for noise than a
low sample rate due to the various noise shaping schemes used by
different ADC manufacturers which shift the noise energy into a less
perceptible ultrasonic range, in which case the audible results are
much better than the lab measurements.
