Hi All,
I have done the total mode and removed BA tweeters completely !
It's the best thing I've ever done with headphones. Sound isn't V-shaped anymore, but neutral, with surprisingly great/smooth/laidback extension to the top end. I really do not understand why the heights are so well tuned now, It's an audiophile dream. Bass and mids aren't affected.
That 30095 BA thing is there for nothing (or for trebleheads )
(If anyone is interested in trying this, I'll write a some tips how to remove it)
I have the CCA C12 which could benefit from the same thing. Easy to do?
