Like you, I have not heard many dacs. Started with a Jolida glass dac and it really didn't sound any better than my MacBook. Bought a Bluesound and started streaming with that. Heard a slight improvement to my ears. Then on to a Denafrips Ares II. Night and day difference (for the better!) over the Bluesound. All associated equipment stayed the same. Of course, YMMV in this crazy hobby! I'm content with the Ares for now.
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?
