I was leaning towards the CM7's when I visited my local dealer last weekend but over the last week with the ton of searches that I have done, I haven't seen any glowing comments on them. The latest review that I found in one of the HT mags this month wasn't the greatest either. Do the CM's stack up that poorly against the "step down" model of the 600 series, which I found the 603's to sound almost the same? Should I suck it up a little on the budget and go with the CDM line? What difference have people heard when comparing the two? Lastly, I want to go with floor standing speakers but can compromise for a better sounding speaker, are the bookshelf CDM's or even Nautilus 805's going to blow away the floorstanders? Thanks for the help. I am using just a mass market DD receiver for now but will be upgrading in the future.
