Go for it, seriously. They're great speakers.
I'm leaning towards the Rotel (from info alone) since I found out that B&W and Rotel are owned by the same parent company, and are generally made to match well.
They share the same distributor. Nothing more, nothing less. B&W's are not voiced using Rotel amps, contrary to urban myth. That said, there's certainly nothing wrong with a Rotel/B&W system

However, I'm guessing at the price range of Rotel amps and B&W CDM speakers, I wouldn't have to worry about muddy sounding vocals.
You are correct sir! However, price has nothing to do with it as there are plenty of fuzzy, muddy sounding overpriced speakers to be had. It just so happens that the ones you bought aren't. Chances are the vocals, especially female, on the CDM's are going to be revelation over your Polks. Hell, I'm excited FOR you!

In the meanwhile, would it be ok to hook up the CDM's to my old Yamaha until I get the amp, or would this be bad for speakers of that quality?
Of course not. In fact, they will probably sound really good. This will give you an opportunity to see the difference a good amp makes, particularly with these speakers. Prepare to be blown away when you connect that amp to the pre-outs. NOW you'll hear what these speakers are capable of.

Have fun and enjoy the music.
