TPA2038D1: cutoff frequency and pop noise

Part Number: TPA2038D1

Hi all

Would you mind if we ask TPA2038D1?

Input coupling capacitor(AC coupling) on TPA2038D1YFFEVM is 0.1uF.

In case of AV = 6 dB   : the cutoff frequency will be 21.2Hz
In case of AV = 12 dB : the cutoff frequency will be 10.6Hz

In generally, we guess that the big capacitance value will be cause of pop-noise.
So, in case of using 0.1uF, as your experience, is it no level which you worry pop-noise?

If you have some advice, please let us.

Kind regards,
