Is that an Air Motion Transformer, or Ribbon Tweeter (on left speaker)
If it's AMT, I'm very impreessed, if it's ribbon... less impressed, he he he he
I love AMT's, there seem so be sth more.... or I would I even say it's sth less... like less distortion.... or just the treble is so much much much better
EDIT: When I look again it says BG (Bohlender Graebener) which means it's ribbon, yes?
