I love them. In short ....it's a clearer sound with the ESP (MusicCord-PRO ES) cables for sure. I can definitely hear a difference. It's actually not subtle.
My mix's sound better, that I hand into labels etc.... less muddy.
I'd like to buy some more. I want another 3 or so more for sure. It's top of my list....
I've been flat out and haven't had a moment to put them in my C12 or Neuman M149, and neither of those mics sound terrible right now :) But I will do.
I've been mentioning them to a few producer mates and they all think I've gone mad.:-)
