Noise levels are significantly lower, with the E-4000 being around 20% less than its predecessor, thanks to a revised AAVA volume control system and ANCC circuit.\u003c\/p\u003e\u003ch3\u003eBalanced AAVA Volume Control\u003c\/h3\u003e\u003cp\u003eConventional preamplifiers use variable resistors to adjust volume, which causes contacts to deteriorate and create grit as well as increase noise at normal volume levels. AAVA, however, produces multiple, widely varying signals from the input signal and controls volume by changing the combination of those signals. This achieves minimum noise at all volume levels without any grit. The E-4000 with its balanced AAVA circuits delivers exceptional noise suppression performance.\u003c\/p\u003e\u003ch3\u003eFormidable Power Amplification Stage\u003c\/h3\u003e\u003cp\u003eThe power amplification stage on both the left and right sides is equipped with a large heat sink and employs five-fold parallel push-pull power transistors driven in Class AB to provide rated, high-power output of 180 watts into 8 ohms and 260 watts into 4 ohms.\u003c\/p\u003e\u003ch3\u003eHigh damping factor\u003c\/h3\u003e\u003cp\u003eThe damping factor represents the amplifier's ability to drive the speakers.
