Answer: whatever pleases “you”
Some don’t like the idea of adding anything extra in the audio chain from the belief that it can only degrade the signal. Others may value the adjustability more, and some cannot discern the subjective significant sonic degradation.
I’ve toyed with the idea of dropping in an equalizer such as a Loki or the Cello Palette Preamp equalizer. Worse case I can simply remove from the audio chain.
