As I pointed out, this is not a limit on S/N ratio. One simply uses higher voltage levels. For example, if one uses 3 volts instead of 1 volt one will pick up an additional 10 dB in S/N ratio. Similarly, one can use a lower source impedance than 200 ohms. (For example, paralleling multiple DAC chips will lower the source impedance and hence the noise voltage.) One can also cool things down as well, but this is common only with high performance RF receiver front ends, not audio circuits.
