Control Amplifiers


We have acquired a great number of technologies for improvement of sound quality through the development of our flagship model, C-1000f. Such technologies have been integrated into newly appeared C-800f, a masterpiece of control amplifier. Our original feedback circuit, ODNF, is introduced into C-800f, which is version 2.4 as the same as used in C-1000f. In the attenuator section that is integrated into the amplification circuit, 4 pieces of "LECUA1000-WM" that has been newly developed for improved efficiency with the signal path are mounted. Various gorgeous specifications are inherited from our flagship model including full-balanced transmission circuit, power supply equipped with current supply source comparable to a power amplifier, and bi-amplification output mode. C-800f can fully exercises its unlimited dynamism and richness of music essence when a high-performance power amplifier such as M-800A is driven.
