BRZHIFI C-200 Preamplifier High-Resolution Hi-Fi Preamplifier Audiophile-Grade Audio Equipment Class A Amplifier With Remote Control

1. Product description

The C-200, introduced by Accuphase in 1973 as its flagship preamplifier, established the brand's early sonic foundation through its design philosophy and circuit architecture. To this day, it remains a subject of admiration among many audiophiles.

The amplifier employs a complementary Class A push-pull architecture featuring a field-effect transistor buffer input and Darlington output stage. The common-source, common-gate configuration minimizes input-output feedback while maintaining exceptional linearity across the high-frequency range. This architecture delivers minimal input-output feedback, yielding outstanding high-frequency performance characterized by high gain, excellent linearity, low distortion, and superior signal-to-noise ratio.

It preserves its signature warm, rich, and dynamically incisive sound while delivering lower distortion and a wider frequency response. This amplifier is not only a tribute to the golden age but also a bespoke audio control center for contemporary music enthusiasts, ushering in a new chapter of high-fidelity music.

2.Internal components

·Classic C-200 circuit

It delivers a stable, reliable sound foundation with pure tonal quality and rich musical character, avoiding the immaturity or harshness that can sometimes accompany new designs.

·ALPS motorized potentiometer

Delivers exceptionally low noise and extended longevity, ensuring smooth and precise volume adjustment; paired with remote control functionality, it offers unparalleled convenience.

·Bluetooth 5.4 high-definition input

Featuring fast and stable connectivity, low power consumption, and minimal latency, it supports high-definition audio codecs like aptX Adaptive. This enables wireless playback to deliver sound quality approaching that of wired connections, significantly expanding audio source options.

·Dual EI transformer power supply

EI transformers inherently possess strong anti-saturation capabilities and low electromagnetic radiation characteristics. The dual-transformer design enables independent power supply for left and right channels, effectively reducing crosstalk to deliver a darker background, clearer soundstage, and enhanced dynamic performance.

·5-band professional EQ adjustment

Empowers users to fine-tune sound quality based on personal listening preferences or room acoustics, making audio more tailored to individual tastes and enhancing adaptability.

·3-in/1-out RCA connectors

Multiple audio source devices (such as CD players, turntables, and TV set-top boxes) can be connected simultaneously and easily switched via the amplifier. Outputs connect to power amplifiers or powered speakers, enabling flexible and convenient system configuration.

This configuration collectively forms a high-quality preamplifier that delivers solid sound quality, comprehensive functionality, user-friendly operation, and high playability. It preserves the core Hi-Fi pursuit of power supply and circuitry while integrating modern wireless technology and tone adjustment capabilities, satisfying the dual demands of traditional audiophiles and contemporary users.

Pounding Heart, Pure Power Supply

Utilizing high-quality dual EI-type transformers for independent power supply, it delivers abundant, stable, and pure energy to both amplification and control circuits. Effectively isolating external interference ensures a deep, tranquil background and dynamic performance that flows effortlessly, laying a solid foundation for exceptional sound quality.

Precision Volume Control

Featuring the ALPS Model 27 high-precision volume potentiometer, this design ensures stable two-channel consistency with minimal coloration and high fidelity. The analog volume control curve, adjusted through this mechanism, delivers smoother, more linear master volume control—making it the preferred choice for high-end audiophile systems.

Relay Switching Input

Omron relay switching input achieves switching speeds ranging from milliseconds to microseconds, effectively preventing sound pollution. Eliminate concerns about sound coloration caused by ripple generated from electronic components.

Qualcomm Bluetooth QCC3084

The newly released Bluetooth communication chip is an upgraded version of the QCC5125 and QCC8675. In addition to supporting aptX-HD and LDAC, it upgrades communication from Bluetooth 5.1 to 5.4. It also supports aptX-Adaptive up to version 2.2, enabling lossless audio support, and supports LE Audio.

We all know that Bluetooth transmission compresses and decompresses audio, and this compression causes music to lose its original authenticity. Many high-quality transmission formats, despite their high sampling rates and bit depths, still employ lossy compression. APTX LOSSLESS, however, preserves the complete audio data bit-for-bit, faithfully retaining the original audio and video. This enables lossless transmission of CD-quality audio (16-bit, 44.1kHz) to headphones for playback.

Carefully designed functional knob

Featuring a professional-grade 5-band EQ system with meticulously calibrated crossover points

(45Hz/100Hz/700Hz/2.5kHz/12.5kHz), allowing you to finely adjust bass impact, midrange richness, and treble clarity according to music genre, listening environment, or personal preference. Achieve truly personalized sound and execute precise, detailed tuning.

User-Friendly Design

This unit features tone bypass functionality, mute, and automatic volume reset (resets to zero automatically within 4 seconds after power-on).

Note: The 45Hz knob is in bypass mode when turned fully to the left.

Premium-grade components

Uncompromising materials ensure low noise and faithful sound reproduction

8.Q&A

Q1: What are the sonic characteristics of the C-200 preamplifier?

A: The C-200 builds upon the tonal foundation established by Accuphase's flagship preamplifier introduced in 1973. Featuring a Class A amplification architecture and field-effect transistor buffered inputs, it delivers a warm, rich sound with dynamic precision. It combines high linearity, low distortion, and a high signal-to-noise ratio, blending vintage charm with modern high performance.

Q2: What are the advantages of the ALPS motorized potentiometer?

A: The ALPS Type 27 high-precision motorized potentiometer delivers exceptionally low noise and extended longevity. It enables precise, smooth volume adjustment and supports remote control operation, balancing high-fidelity sound quality with user convenience.

Q3: What high-definition audio formats does Bluetooth 5.4 support?

A: The C-200 utilizes the Qualcomm QCC3084 Bluetooth chip, supporting high-definition codecs like aptX-HD, LDAC, and aptX Adaptive 2.2. It pioneers aptX Lossless transmission, enabling wireless playback of CD-quality (16bit/44.1kHz) lossless audio with sound quality rivaling wired connections.
