“The attack of the notes, or instantaneous dynamics, is frank, fast and realistic. Here, by the way, is all the interest of listening to musical tracks that we know well to get a precise idea of the naturalness of the This integrated amplifier is very precise and lively, releasing the full harmonic content of each transient sound which, as everyone knows, is dependent on the rapidity of the rise time. Note that attacks are reproduced in optimal conditions since the amplifier, having instantaneous energy to spare, reacts without audible recovery time.”
