Just picked up a D800+. Great sounding amp, but one issue I noticed- when the limiter light kicks in, it makes an audible clicking/ clipping noise through the speakers. Is this normal for this amp? no overdrive or distortion through the speakers. Just the limiter kicking in on really low notes. i don't mind a limiter doing it's job, but this does not sound correct. Anyone else have this type of noise when the limiter kicks in?
