I'll third the Vandersteen 3A signatures. They are one of the most MUSICAL speakers you will find.
I currently own Apogees and used to own Vandy 4's. They're very different animals... The Apogee's resolve to the nth degree - fun if you enjoy picking apart components, cables, recordings, etc. When everything is right, there is simply nothing better out there IMHO, but if anything is off (recording, component, etc.) they really show it and it's hard to simply sit back and enjoy the music.
The Vandy's (I've spend quite a bit of time listening to both the 3A's and the 5's) are simply very musical. Both use the same top-end components. At first impression, they seem very laid back (almost too much so) but what you find after spending time with them is that they envelope you in very lush, warm sound. They suck you in and you find yourself listening for hours without realizing how much time has gone by... This is their magical ability.
From a soundstage perspective, they throw about the largest of the dynamic driver speakers that I've heard. If your electronics are good, the stage will extend significantly beyond the outer sides of the speakers and easily 10 feet back in depth. Again, it takes good electronics to make them really sing....
Richard Vandersteen has a theory about using only first order crossovers (6db slope). His theory is by using first order crossovers, that the phase is maintained throughout the audio spectrum. I believe there is something to this based on what I've heard....
These are just my subjective impressions. Find the 3A's and spend some time really listening to them. Everything music wise is there and in its proper place time and space wise with them being at all fatiguing.
Good luck,
Steve
