Out of the 5 songs I listened to I gave the edge to speaker 2 (M3) for four of them. I owned Vassallo M3's and currently have Algonquin M3's and could not believe that was what I was listening to.
I was really surprised by the imaging difference, the speaker 2 (M3) extended out so much further to the sides. I originally thought that speaker 1 was M3 and speaker 2 was M22 due to the difference in the highs.
The only song that sounded better to me on the B&W's was Holly Cole "I can see clearly now". This was the first time I had heard this version and I could have listened to it over and over again, which I did. For this song I think I liked the bit more laid back cool sound?
Regardless performance to price is a no brainer for me.
