Yup. Most people think all components as the same cause they have the same general classification. DAC, amp, etc. Spending more is only a vanity of the "idiot" and isn't any better than what "we" have. So we blissfully ignore anything above our station as extravagance.
even if these people try the gear in a meet or anywhere else for a short while they won't notice the difference because such things need time to sink in, especially when all is volume adjusted.... for example if someone has used some sort of budget friendly receiver (500-700$ range ) for a year or so with say..... the he-6..... and then tried his headphones at a friend's place on a receiver 8x the price he'll notice a difference,yes and he'll like that receiver but after hearing the price he'll subconsciously back off slowly .... BUT, if he supposedly borrowed that receiver and used it exclusively for an entire month,returned it and then plugged in his old receiver he'll think that it's broken, or that something is definitely wrong and that it's not the receiver he's used to listening to(like the life of his music has been bleached off) , that's likely because his ears have figuratively matured enough to tell vaster differences between his system's components and he knows(more than before) what to hear in his music and what to look out for, and this is especially prominent when downgrading after a long time of using good equipment .
