Accuphase C-57 — Balanced Phonostage with Dual Mono Topology
Accuphase has introduced the Accuphase C-57 phono preamplifier, based on a fully balanced circuit design from output to input with dual mono topology. The Accuphase C-57 also uses a two-stage solution: the first stage is the output stage to ensure matching with MM and MC cartridges, the second stage is the correction amplifier itself.
The Accuphase C-57 is based on the proprietary original ANCC solution, which provides minimal distortion and noise levels due to the process of comparing signals at the input and output with subsequent suppression of interference introduced by the amplifier itself.
The Accuphase C-57 phono preamplifier supports 7 load options for the MC cartridge and 3 for the MM. The power supply with a 15,000 μF smoothing filter is assembled with a huge power reserve - so, there are two power transformers here, for the right and left channels. With a gain factor of 50 dB for MC cartridges and 20 dB for MM, the Accuphase C-57 looks simply brilliant.
