I am just comparing the sound of my Wilson Sophias and WP7's with a variety of amps, both SS and tubed. IMO the BAT SS amps do not produce a soundstage on the level of some ARC, Cary, and Conrad-Johnson tube amps I tried, nor is it in the same range as my Essence SS amps. Before I heard the Essence amps I never heard a soundstage with SS amps that approached that of tubed amps either. Don't get me wrong, the BAT amps had a very nice sound with an iron grip on the bottom end and good dynamics, but soundstaging was not its strong point. An Absolute Sound review about a year ago said the same thing about the VK-600M SE. Maybe you can get a big soundstage with the BAT amps as one other poster said through system synergy but I never heard it myself.
