I have heard the WP7's and the Eidolon's. I have not heard the JM Lab Alto BE's though.
That being said, the Eidolon is one of the finest speakers I have every heard. A friend has some and has a similar set up to your own. He has the same turntable, and runs all tubes as well (ARC Ref. 1 preamp and VTL MB-450 monoblocks) and he uses a Koetus Urushi with a Aesthetix Rhea phono preamp. It is the finest stereo I have heard in my life. (This probably includes stereo dealers and stereo shows, since he has a fairly large dedicated room for his stereo.)
The Eidolons have the rare ability to just disappear from the soundstage. Mid-range and treble are great. The bass is very, very good (it goes down flat to a little below 30hz), but does not go quite down to 20hz. (Plenty deep for most people as only the very largest of rooms can really handle deep bass without sounding boomy.) As far as looks go, it is awesome looking, especially with one of the "fancy finishes", like the bird's eye maple.
The WP7 is a good speaker and it excels at accuracy. It soundstages well, just not as well as the Eidolon, IMHO. Its looks are ok, but not really in the same class as the Eidolons. (But then again, what is?)
I would definitely pick the Eidolons before the WP7 myself. I like the WP7, but love the Eidolons.
My two cents worth anyway/
