Hi Cyrus,
too bad but Jan. isn't that far away, when you spoke to Robert did he recommend the SP1-A over the SP1's I currently have.
If so why? Did you inquire about the all brass unit's that Rick from Virtual Dynamics mentioned above in his thread referring them to "STAGE"
I actually pulled up some pics from a show dated back in 2006 showing these platforms from Sound Star "Sistrum" and noticed Virtual Dynamics was actually also exhibiting in the same booth.
Check it out, just go to the bottom of the pics and then up a few and you will see them, some good pics.
