I think the best way to decide how you like any new component is to live with it for a while. If you don't like it, it will become obvious quickly. If it's close, you can go back and forth and compare. Play lots of different music- see if you enjoy things you hadn't with the prior component. This seems to be the way reviewers do it.
How easily can you distinguish between different DACs?
When I read reviews or watch them on YouTube the reviewers talk about the vast differences between various DACs. I haven't compared too many, but found the differences pretty subtle, at best.
Which got me into thinking: Is my hearing ability really that bad?
Do you notice the differences as easily as folks make out?
