Ah... so it just a subjective evaluation there... because i compare the data and cant find the answer. Surely if you want to compare it (subjectively), should be under the same system and test, otherwise it will mean nothing.
@amirm based on the intermodulation distortion test, is it true that it will give the lowest distortion if i set the D70 volume to around -13dBFS? I use another preamp (with volume control) driving my amp currently.
