Accuphase C-57 Phono Equalizer Amplifier
Fully Balanced Design for Vinyl Purists
The C-57 phono equalizer amplifier embodies Accuphase’s relentless pursuit of analog perfection. Featuring a fully balanced architecture from input to output, the C-57 preserves every detail and nuance of your vinyl playback. Its dedicated MC/MM head amplifier is precisely optimized for cartridge compatibility, while the groundbreaking integration of ANCC technology in the MC stage dramatically improves noise performance. With the C-57, your turntable becomes a gateway to pristine analog sound.
Precision Meets Flexibility
Every design choice in the C-57 is tailored to extract the maximum potential from your vinyl collection. From its ultra-low-noise regulated power supply to its high-accuracy RIAA equalization with just ±0.3 dB deviation, the C-57 ensures faithful reproduction of the original recording. With four independent phono inputs, seven MC and three MM impedance settings, and separate memory for each input position, the unit adapts seamlessly to a wide range of cartridges and playback needs.
Premium Build with Audiophile Integrity
The C-57’s monaural construction layout, toroidal power transformer, and glass fiber cloth fluorocarbon resin PCB ensure uncompromising signal integrity. Balanced and line-level outputs provide flexibility in system integration, while the phase selector and gain adjustments allow tailored tuning. Housed in an elegant chassis with aluminum finishing, wood grain side panels, and high-carbon cast iron insulators, the C-57 offers both sonic brilliance and visual refinement.
