Ability to let source components be heard accurately without adding any of it`s own 'flavour'. Very powerful.

Musically,none. Bulky and heavy (if thats a problem)

I purchased the Dual 4 together with the 11 pre and the 12 psu.After owning amps from Arcam,Naim and listening to a vast array of other makes, I realized dual mono and total channel separation from the dac to the speakers was the way to go.This is a very honest and powerful sounding amp set up . It is vertually transparent in a way that it wouldn`t be out of place in a studio monitoring system, of which I have heard a few (being a professional musician)!
