The tradeoff of 192 kHz sampling

Hello Toki and All,

AK5394A sounds really great although...

I'm not an expert in this field though one who interests in more technical
should read;

It summarizes;
On the other hand the study of the technical specification of the AK5394A
indicates that the S/N ratio decreases at higher sample rates as a result of
the expansion of the frequency band. Actually the S/N decreases by more than
3 dB that one would expect as a result of a doubling of the sample rate from
96 kHz to 192 kHz.

So, what?
