All meddling with the source signal introduces sound degradation, whether in the analogue or digital domain. Tone controls, bass & treble adjustment, speaker crossovers, Dolby, equalisers, click and pop eliminators, MQA-like processors. All the same.
It is impossible to adjust the sound without introducing distortion.
That is the reason for the unlifelike presentation that many people hear in digital, compared to the more lifelike analogue presentation. The main direct causes are DA converters and clock dither. These faults can never be fully addressed, as has been shown in the 40+ years since digital recording started.
Simple is best, leave well alone.
