distortion figures can teach us some things but not everything (don't forget slew rate, noise floor, current capability, crosstalk, EMI/RF rejection, power supply ripple rejection, etc);
I've had my share of amps with low to super low distortion figures (and in the case of the Benchmark amp significantly!) on the test bench when subjected to single frequency sine waves, and each has a sonic signature;
In the final analysis, though, the one that really ought to matter, is: does it sound like the real thing with your system gear? Does it tend to make you want to turn up the volume because you can't wipe the smile off your face and you need more? Does it help you forget that you are listening to electronics? Does it speak to you emotionally? Pass is at least one amplifier manufacturer that has gotten this way right; They are popular for a reason!
Pass for President! (ok sorry for that, lol)
