Where do you live, have you checked the audition thread? Or, you can send a PM to Amie or Andrea at Axiom, they sometimes have people that will audition but don't have their names on the list. Or if you say where your live, there could be someone on this forum that does not have their name on the list.
For me I thought the m60's had a little better in the low end (bass) and more detailed highs and midrange. If I recall, the B&W's had a kevlar woofer? I prefer aluminum construction. Plus I could purchase 2 m60's for about the same price of just one 703. Also, customer service was very important and it is hard to beat Axiom on that...
