Given the high DAC output, the question arises as to what the signal requirement is at the amplifier input? Unless it is down at the low millivolt level, just about any resistor would do, as the thermal noise of the resistor would be well below the signal. As Mr. Hennessy points out, keeping the values low would be an advantage.
