These are very nice units. If single ended, choose the 10K ladder or series. For balanced, choose 10K series.
Anything higher than 10K creates an output impedance too high. A high output impedance combines with the capacitance of the interconnect (to amp) and amplifier input. This creates an RC lowpass filter which will attenuate the top end if the capacitance and the output impedance are high.
