Hello again.
I thought that it was interesting when you said that you heard the Totem and the Energy speakers at the same store. Where I live, one of the well known high end stores also carries both Totem and Energy, as well as Arcam. That's where I heard the Arcam/Totem combination. I would anticipate that the difference you heard between Totem and Energy would be what you would hear if you compared Totem to Paradigm. That's one of the reasons I suggested that Retailer 2's system would be a bit better than Retailer 4's.
One other point on the speakers being placed in the wall unit. Ask the retailers what they think about the bookshelf placement for the models they carry. It's not going to be as good as a stand mount, but it may still sound pretty good. For example, if the speaker is a sealed unit (i.e. no port), there will not be any backwave bouncing around in the wall unit. And if you put the speaker on some cones to try to isolate vibrations into the wall unit, the speaker may perform in a satisfactory manner. In addition, even if the speaker does have a port, the speaker designer may have intended that it be placed close to a back wall in order to reinforce the bass. If the particular model is such a speaker, having it close to the back of the wall unit may not be too bad. You would still be advised to put it on some cones on the shelf however.
The point you made in the last paragraph about low volume performance is also important. I find that the performance of some speakers is quite different when played at low versus high volume level. The monitors which I have need a little bit of volume before they start to perform really well.
