I too am not a B&K dealer. My front soundstage consists of a pair of Klipsch RF-63's and an RC-64. With my B&K Reference 4430, bright these Klipsch's are not. Very warm sounding but with plenty of authority. As mentioned before, these amps are built like tanks. Cool running,low noise, and plenty of reserves. It handles low impedences with ease.
