If I were you, I’d demo a broad range of DACs in your system before making any judgements, either about the gear or your ability to discern differences.
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?
