Accuphase C-47
The C-47 is the first phono amplifier of this series which realizes a fully balanced configuration from input to output. The resulting product not only is highly impervious to external noise, it also features a dedicated head amplifier optimized for the characteristics of MC and MM phono cartridges, and a high-accuracy equalizer amplifier, thereby ensuring precise equalization with a minimum of noise. A set of newly added dedicated balanced MC phono inputs enables balanced connection to the analog record player. By bringing out the full performance potential of each phono cartridge, the C-47 delivers a rich and deeply satisfying musical experience.
