Any new speaker on its way to your door step is exciting IMO! Here I am sitting 15 feet from my almost 1 year old M80's and I'm wishing I could be at your house Monday when your M50's arrive!
It's a great experience listening to a new set of speakers to see how well they fit into your listening area. Though it has a different design than their top-of-the-line models, the M50's are still made by Axiom, so I'm sure they are a fabulous speaker in their own right. So have fun demoing them, and if by chance they aren't what you were hoping for, you could always return them and perhaps try the M22's or M60's.
And if the are what you were hoping for, well then you will be a member of a very select group indeed! Either way, congrats!
