Welcome TX
There actually has been a lot of talk about Axiom vs. B&W around here in the past, I'm sure if you try searching for B&W, it will turn up many posts...
Anyway, for me when I was looking a year ago I thought the M60ti's sounded similar if not a little better than the 703's. I could not justify the cost difference. I think the M80's would also be in that same category or better. Everyone is different though, so an audition in your area would be the best, you might want to check the Audition thread in the "Hearing Things" forum.
