Well, I don't think you can apply it that easily. But generally people do underestimate the power of a DAC, albeit I withheld from them because I just couldn't find one that I liked. Mid-fi is easy, trade headphones till you find sound you like a simple Portable solution is fine... But I see a lot of people with 1k + headphones with a 300-ish portable DAC/AMP. What are you doing + pure silver cable... WHY?!
