Hi,
Could you please let me know if there are any disadvantages when LGRP is set to "1" (low group delay)?
For example, SNR, distortion, sound quality, etc.
Best regards,
Kato

Hello Kato,
By definition Group delay of filter is a measure of phase distortion. Group delay is the actual transit time of a signal through a device under test as a function of frequency and causes amplitude distortion. The below link is a good reference to understand and visualize the effect of group delay on signals and how it changes them.

Having said that, data sheets for audio range devices usually don't have different values for THD, DR and ... based on selected group delay.
