E-4000 integrated stereo amplifier emerged separate amplifier technology accuphase after covid 19

E-4000 integrated amplifier has emerged from separate amplifier technologies. The preamplifier section features  AAVA using ANCC to allow for volume adjustments that maintain high levels of vibrancy. The power amp section employs balanced transmission utilizing the instrumentation amplifier principle to drive noise suppression to its limit.  The E-4000 is equipped with a four-fold parallel push-pull configuration of power transistors driven in Class AB in the output stage to extract every last ounce of potential from the speakers and create soundscapes filled with subtlety. An integrated amplifier crafted from separate amplifier technologie driver it can driver all speakers including JBL L100 Sansui potentiometer Conventional 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 levels at all volume levels without any grit.
