Had the demo yesterday- very,very nice amps heard the Dialogue HP and Prologue Premium, and am in the process of a home loan with PRologue Premium ( Dialogue HP extra power not required as it turns out) the Dialogue Premium was unavailable to listen to yesterday, so have to decide between the Prologue and Dialogue there is a believe a bit of a price hike between the two amplifiers, l have been advised that the Dialogue has a bit more grip and control, can anybody chime in?
