The subjective part is what is the problem. There are no sound or tonal characteristics except for the relevant measurements, as that is what the measurements are made for and they do cover enough of the performance range that one would care for.SIANDs demonstrate that the engineering team showed care in designing the unit. It doesn't tell you the whole story on sound tonal characteristics. Also, that part is really subjective. It comes down to taste.
That is why for some it might be a bad taste to argue otherwise, especially on this forum.
