I probably should have explained my reasoning for the choices I made a little better.
First the speakers. When you place speakers against a wall, you get a significant boost in the bass due to boundary reinforcement. There are a number of speakers specifically designed to take advantage of this. The first that comes to mind are some of the Audio Note Speakers. Putting those aside, you say the CM B&W's are a bit bright. I realize that, that is why I suggested the bookshelf B&W's. Placed against the wall, the boundary effects will (hopefully) offset those B&W's inherent brightness, lifting the bass to a point where the sound 'evens out'.
Next, to combat some of that same 'brightness of the inexpensive B&W's I suggested a vintage tube integrated. They (unless somebody goes overboard in the rebuild) tend to have that 'tubey' sound. Read=rolled, less defined highs, but a great and lush sounding midrange. Again, taming the highs even further.
Next I suggested a stock Squeezebox. The stock SB is rather pedestrian sounding. Read = a bit rolled and less defined highs. Again, helping to tame the highs.
The other item I mentioned is the benefit of tone controls. You are setting up a listening system that doesn't conform to traditional audiophile rules (ie; pulling speakers out from the wall, specific spacing between, trying to image, etc,). It is going to be extremely difficult to get an even sound top to bottom with the listening system configured as you plan. Even with the suggestions I've made, the sound could be a little lumpy in places. The tone controls will help smooth out some of those lumps. I would have suggested an EQ but that is going a bit far for the system you are assembling. The trick to the system is balance. Forward sounding speakers and relaxed sounding front end......balance.
One thing I can say with reasonable surety is that an integrated without tone controls, especially a T amp, is only going to sound reasonably well on certain types of music with the system set up in your configuration. The rest of the music will [likely] sound thin and anemic. If it were me, I'd pick something that has some sort of tone shaping ability...but that's just me.
