Yes the Gallos sound nice(almost like NHT superzero's sonically, but a tick less treble extension). However, sounds like this gentleman is considering more upscale and refind speakers overall. If I were you, I might consider going to audition the Maggies on wall "thingies" I certainly know the Infinity MTS towers will sound nice for you, but pricy indeed (but worth the money I think). Also, the Thiel Powerpoints are excellent onwalls sonically. And they have a sealed box inwall version(at least much better than other inwalls by far)
Also, what kind of music are you most after?
Anyway, my best suggestion would be to avoid the whole "inwall" thing, and get over to the CES show in January! Then, you can audition more of what you're possibly looking for, and make a better chioce. Is this workable? Also, you get to go to Vegas for the trip...not too shabby.
