As long as you can't hear a difference, your wallet is safe from amps and DAC's basically is what I mean.
And to be fair, I'm fine as long as the DAC and amp in my systems and computers are within tolerable levels for general use....it seriously doesn't concern me. Obviously I would prefer to have better ones. And I have a shelf full of them. But in public or on the go, all the stuff in public is fine enough.
Noisy amps, high distortion, added effects, clipping and all that schiit?...HELL NO.
