The warp frequency for records is 0.55 Hz.
Having a cut-off above that frequency will cause the capacitor to constantly charge and discharge due to the warp frequency excitation.
That kind of excitation will maximize the capacitor's dielectric signature, and exaggerate it's faults and foibles.
Without knowing if there is any upstream filtration, it is better to avoid the problem and keep the corner low.
CD and most other sources have built-in limitations for extreme low frequency response, and are generally incapable of generating such a consistently repetitious signal with nearly every playback event.
Just my take on the matter, and there are arguments for the opposite approach and filtering out the warp frequencies to the point of cutting into the audio band a little. Just remember to use a perfect capacitor in that case!
