[QUOTE="AV, post: 25718, member: 472"] To me a high DF is an indication of the capability of an amplifiers PSU as well as output stage to drive a difficult load, unfortunately high levels of NFB can also make the figures look good but can harm SQ. A high DF is not only important in the braking of a driver but also shows the amp's capability to drive a complex speaker load more accurately. I'm not trying to link my observations to a high DF alone, surely there are more that can influence the SQ but I believe DF has an important direct or indirect influence on the sound. My observations were made with different amplifiers and I found that an amplifier with a high current PSU and output stage, therefore high DF, could drive a subwoofer at much higher SPL giving a more defined bass with less cone travel. To me that show that the speaker was more accurately [b]driven[/b] and [b]controlled[/b] by the amp. [/QUOTE]
