Just wondering, how can i know if a DAC is good or bad, is there a way to Benchmark?

I remember using some kind of software from Speaker Output to Line In to compare, but not sure it that was testing the DAC or something else.

Thanks

RMAA software to measure SNR, distortion, frequency response, crosstalk, etc. is the easiest. More elaborate measurements are possible, but require dedicated equipment.

Thanks, just found it.

But i donīt really know what the stuff means,

24-bit. 48 kHz

-0.04. -0.11
-85.8
80.7
0.0047
0.016
-85.8
0.015
+0.0. -0.0

This is the results i guess, is it good or bad?

Wikipedia is a great place to look up what things mean. Alternatively, you can ask here, although wikipedia is probably faster and better.

Its hard to say since you posted the numbers but not the labels indicating what those numbers refer to. 80.7 is pretty good for SNR, not so good for % THD.
