It seems it's got a longer throw than the AE500, but that's not a problem in my set up.
Price not fixed yet but it's in the region of another £1000 on top.
I buy lots of stuff from this place so they try to keep me happy, rather than just simply let me try and buy. However, I don't really want to get the Sony (as I haven't seen it in action yet)and then decide to go back.But if it's that much better than the 500 then I don't think it'll be going back
