lol calm down.Amazing, you are so confident like saying 1+1=2 on the technical detail of Cayin C9.
Apparantly you know so much about C9, a lot more than I do. Do you have access to technical implementation of Single end to balanced coversion and balanced to single ended conversion of C9? Or you assume all conversions are the same? You know one, and you know it all?
You really are extraordinary.
Do you have any idea on the different between High gain and Low gain of C9? 6dB? 9dB? 12dB? 16dB?
As you mentioned in a previous post somewhere, there seems to be a overwhelming belief in Headfi that Balanced is always almost twice as good as SE which is not always the case especially in 2-ch systems. Can't really change the belief overnight even if you release a product that has better SE than BAL(which I am not saying C9 is)
