Precision Stereo Control Center
The Accuphase C-3850 now concentrates the extensive know-how and expertise gained over the years in the field of preamplifiers into a product that is destined to become the new reference for the next generation. Both in concept and circuit execution, this preamplifier stands at the very forefront of technology.
Foremost among the distinguishing features of the C-3800 is the further evolved "Balanced AAVA" concept. Two AAVA circuits are driven in a balanced configuration, resulting in ideal volume control behaviour from balanced input to balanced output. The complete path for all signals from the input connectors to the outputs is fully balanced, ensuring utmost purity and further improved electrical characteristics.
