Of the speakers you listed, the Ravens are the only ones that are truly full-range, going down to 20 Hz. I have a pair of Raven Cs, and they are just amazing. Easily the best speaker I have had in my system, and one of the best I have heard. They are actually 2-way and image like small monitors.
I was dubious before I heard them, and was worried that the midrange would suffer from having just a 10" woofer and a 1.5" tweeter. It doesn't. They are seamless top to bottom, and fast, with awesome bass. They compare very favorably to Talon's 40K firebirds, which I have heard in a very nice system. If you haven't heard true full range speakers, you will be in for a surprise. They reveal bass which is simply not present in most other speakers.
They are quite heavy (>150 lbs each), and impossible to knock over, unlike all slim floor standers. The are also not the best looking speaker of your group.
The Vienna Strauss are also fine speakers-- I was actually the original owner of the pair on Agon right now. They are not warm in a bad way at all, and overall very nice speakers to listen too. Completely non-fatiguing. Bass is decent, but in no way full-range. They are also difficult to set up correctly (probably owing in part to the side-facing woofers). This might be an issue for you because it sounds like one speaker will be in a corner, and the other in the middle of your room. But it can be done with a listener, and somebody to move the speakers.
The Strauss are also beautiful speakers. If you didn't know, both the front and back panels (and about 1" around the sides) are piano gloss black, while the rest of the body is black ash-- a very nice effect. You can also use the spikes in a 3 or 4 spike configuration, which is a feature that I really like. However they are tall and would be easily knocked over by children.
I have heard the Gallo Ref 3.1s in several systems, and while they image very well, I thought something was missing from the mid-range. The bass also was not impressive, but I have not heard them in the active configuration which supposedly really improves the low end. Also this was when they first were introduced, and I think some improvements have been made? Of course many others seems to like them much better.
The newer Sonus Grand Pianos I heard at a dealer, and was not impressed. I also have heard some of mid-range Amphions at a dealer (not the Xenons, they had already been discontinued), and personally would stay away from them.
I have not heard the other speakers on your list, but would love to try a pair of Adagios. But I can't imagine them competing in the bass category. Also it seems like it would be hard to go wrong with just about any Dynaudio Contours, as long as you have the amplifier power.
