Thank u very much. I look forward to trying the filter 9. Am I wrong or in the manual u get when u order there is no info about the different kind of filters? Will the filter 9 be better than i.e. filter 5 even when listening to 96khz audio (i.e. blu ray or dvd)?
I also look forward to trying the filter 4 for listening to bright recorded music (very often pop and metal).
