Indeed. If you want colouration, then why not go all in and do what music producers do, and use the usual ubiquitous "soundgoodizer" effects? At least those are adjustable and don't limit you to one specific characteristic. Prime example
That (old and rudimentary) BBE Sonic Maximizer works wonders, subjectively. This kind of simple and basic effect that can be had in software for free has a much greater impact on the overall sound than all differences between reasonably well designed DACs, preamps, and amps. Because it's radical in the literal sense: grabbing the problem by its root.
