OK...take a pause here as you are probably getting advice overload. Time to browse through the product info so you do actually know what these units are. Pointless trying to digest SQ opinions if you aren't sure what's what.
From where you are head mainland to see Gerry (Phase3) or Richard (Reading 7oakes). Both these guys know their stuff and can let you hear what the units will do. It doesn't matter that they might not have an 808.2. You have to judge what you hear. I don't think anyone here has listened to 808.2 and MS600 in the same room at the same time.
As Ronnie says it will be a very worthwhile investment of time and travel money.
