I've spent quite a bit of time measuring headphones on our lab's Audio Precision tester and Head Acoustics Aachen head, and I knew it would be very difficult to replicate it's measurements. In fact, I almost abandon the idea right from the start. I really thought it wouldn't be remotely useful, but somebody had to give it a try. And now that I'm a professional headphone geek, I thought, "Why not?" Boy am I glad I gave it a shot!
