I loved MS1i I bought last may, but Head-fi is full of temptations and I was attracted by all those threads about MS1000, so I decided to buy a kit from Jaben (the red aluminum one).
What can I say? They worth every euro I've spent and I love them more than ever. 
 
Sorry for my poor english, but if you'd like to have a wider headstage and a little more bass on your MS1, try this mod.
Classical music won't be a mirage anymore..
