How easily can you distinguish between different DACs?

Speaking of Corolla Ferrari comparisons, I think what has to be kept in mind is that when you take a cheap and expensive dac "out on the track" you find out that the Corolla dac with it's cheap tires and regular gas is keeping up with the fully decked out Ferrari dac with it's premium fuel and tires just fine. So the difference would be that the cornering somehow just feels better in the Ferrari and so is a more enjoyable experience that justifies the cost. On the test bench, these cheap dacs are performing brilliantly.

yup, you got the answer - try in own audio chain to see if you “subjectively” like the change. Audio chains, power, rooms, and especially preferences are so unique that it’s best to try in your own audio chain.

DACs use similar standardized chip sets. So the differences will be in the analog conversion, which in theory is also a standardized algorithm. However, some manufacturers don't follow the standardization and do their own inaccurate conversions. According to the book Schitt Happened, Schitt used to program their analog conversion by ear. In effect, turning their DAC into an immutable tone control, which IMO is definitely not the purpose of a DAC.

Having been a programmer who has written conversions in other areas, I understand that there isn't anything magic about it. It's either as accurate as the standardized algorithm allows it to be or it's inaccurate. Which means you shouldn't hear a difference between properly programmed DACs.

True, looking at this as software. But ever subcomponents… resistor, capacitor, and turn on the circuit board… the distance between the power supply and all the other subcomponents, the resistance to vibration from the outside world makes a difference in the sound. So, any given chip set can sound very different given the circuitry and environment they are dropped into.

+1, @ghdprentice on implementation. I’ve heard some of the perfectly measured DAC’s and they choke the life out of music.
