Accuphase C-2400 Preamplifier

The Accuphase C-2400 is a high-end stereo preamplifier designed for audiophiles who demand exceptional transparency, precision, and musicality. Introduced in the early 2000s, this model reflects Accuphase’s philosophy of combining advanced engineering with timeless build quality.

At the heart of the C-2400 lies Accuphase’s innovative AAVA (Accuphase Analog Vari-gain Amplifier) volume control system. Unlike traditional volume potentiometers, AAVA adjusts signal gain electronically without degrading the signal path, allowing volume changes without loss of signal-to-noise ratio or added distortion.

The preamplifier features a fully balanced dual-mono architecture, with separate power supplies and circuit layouts for the left and right channels. This design significantly improves channel separation, reduces noise, and enhances stereo imaging.

With an extremely wide frequency response of 3 Hz to 200 kHz and ultra-low distortion of approximately 0.005%, the C-2400 delivers highly accurate sound reproduction with exceptional clarity and depth.

Additional features include tone controls, logic-controlled relay input switching, and the ability to add an optional phono equalizer board for vinyl playback, making it a versatile centerpiece for high-end audio systems.

The Accuphase C-2400 remains highly respected among audiophiles for its refined, natural sound signature and luxurious build quality.

Accuphase P-6100 Power Amplifier

The Accuphase P-6100 is a powerful stereo power amplifier engineered to deliver extraordinary control, dynamics, and musical realism. It was developed using technology derived from Accuphase’s flagship monoblock amplifiers.

This Class-AB power amplifier uses eight parallel push-pull MOS-FET output devices per channel, enabling extremely stable operation and high current capability for demanding loudspeakers.

The amplifier delivers impressive output power:

110 W per channel into 8 Ω

220 W per channel into 4 Ω

440 W per channel into 2 Ω

up to 700 W into 1 Ω (music signal)

With a damping factor around 500, the P-6100 provides excellent speaker control and tight, authoritative bass response.

Accuphase also employs its MCS+ (Multiple Circuit Summing) technology and current-feedback amplification topology to reduce noise and distortion while maintaining outstanding stability and sonic purity.

The amplifier can also be bridged into mono mode, allowing a pair of units to produce extremely high output power for large loudspeaker systems.

Built with a massive toroidal transformer, large filtering capacitors, and Accuphase’s iconic champagne-gold chassis, the P-6100 represents the brand’s dedication to precision engineering and long-term reliability.

✅ Together, the C-2400 and P-6100 form a superb high-end pre/power combination, delivering exceptional soundstage depth, effortless dynamics, and the smooth, refined sonic character that Accuphase is famous for.
