Congratulations Joost!
Wow! There is nothing like trying them out in your own environment. I have not had the pleasure of hearing mine on the Burmester 911's yet. I can't wait for that to happen. These are amazing speakers. My neck was sore for the first week because I kept turning my head thinking I was hearing things to the left, right and behind me. Totally unreal. I absolutely love mine. Keep us updated. BTW, your girlfriend has excellent taste
