Could someone explain why this is worth ~600$ compared to something like AudioEngine's D1? I see that this one can switch outputs with the press of a button, but surely that isn't all for ~400$ more?
KyleLIt comes down to more than specs. These DAC/amps all sound different and the better sounding ones come with a price. And, the CEntrance DACMini PX also has a built-in amp that can power speakers that the AE D1 does not have.
