One of the members of our audio club (Las Vegas Audio Club) has a pair of these, they sound great! The amps: 1000 W Crown industrial amps. I heard this system cranked. You'll be picking your jaw up off of the floor.
I have the JBL S4700s, which are, for the most part, equivalent in sound to the 1400 Arrays, and there might be something to using high powered solid state amps with these very efficient speakers. I'm looking at the Accuphase A-70, which is a Class-A lower powered amp, but can drive very low impedances. It drove a pair of very insensitive Magico speakers @ CES 2015 with no problem at all. But that Pass Labs X350.5 and .8 has gotta be one of the best, if not the best high powered stereo A/B amps out there...I would get that over the Bryston, but the Bryston is a good choice too, and it's a bit cheaper as well...
