Exactly what I'm looking at. I have heard the PS1000 and for the price we have here ($2000) I'm not all too interested. However what I am interested in is the Alessandro MS Pro and using the distancers plus G cush mod. For me the RS2 and SR60i were too peaky in the treble for me.
The first pair of MS-Pro's I had were modded with distancers and gs1000 pads by myself. I liked them but later ended up selling them. I did miss them immensely, so bought another pair. This time around I am keeping them stock. I really like them stock :).
