Should I upgrade from B&W CDM 7SEs to Quad 22L2s

I have endured my current setup for about a year now. Been in this addiction for about that long. I am driving the B&Ws with a Rotel BB-1080. Source is a CI-Audio VDA-2 fed by a squeezebox, with a Monolithic PA-1 preamp. I am about to upgrade my amp to an Odyssey Stratos Stereo with upgraded caps. Wanted advice as to whether I should change out my speakers for the Quads. Don't know where I can audition the Quads here in Minneapolis, so was hoping to get some input as to the virtues of going ahead with this switch. My main problem the B&Ws is its harsh treble. I am hoping the new amp will smooth it out, but I am pretty pessimistic about that. Will the Quads be less treble heavy, and overall a better speaker. Thanks in advance for all counsel.
