The model has been changed from the C-2820 by making full use of the latest technology, and the change is the unique AAVA volume control section. Similar to the C-3850, the V-I conversion amplifier for the highest bit has been enhanced from 2 para to 4 para. Also, when a low noise operational amplifier is adopted as the I-V conversion amplifier, a re-examination of the resistance constant is added, and the resistance is also a low noise type, so you can hear a completely different sound.
