Is it worth upgrading B&W DM303 to B&W CM2?

I currently have B&W DM303 and Cambridge Azur 640A V2 and 640C V2. I found an almost new pair of B&W CM2 at a good price. Like I said it in the title, is it worth upgrading DM303 to CM2? I mostly listen classical (chamber music 70% and all others 30%).

Thanks in advance.
