Here's one more example for you that may help in your selection. You picked your B&W's for a reason. On paper, your CDM 1NT's look like countless other small speakers. You can find another pair of speakers of a similar design and specs, and for much less than what you spent on them. The reason you went for the B&W's is because you like the way they sound. You took the necessary step, and crossed over from the objective to the subjective. If you didn't do that, you couldn't justify the purchase. It's the same thing with any other component. If you set some goals as to what you expect from a new amp or integrated amp as far as sound quality, it will be a great help. You can still make a mistake, but you lower the chances. Try not to worry too much about the specs. I think you easily have the ability to make a sensible choice as to how powerful an amp you need. If you're not sure, just post what ever amp you are considering, and someone here should be able to tell you if it will drive your speakers, or not.
One last thing. Don't get sucked into the cable trap. Cables do make a difference, but so many people put way too much money into cables when it could have been used to buy better components. Not only that, but if you get good components and match them well, cable choice is very easy.
