Design and Engineering

The CS1 utilizes a Class AB amplifier circuit combined with a power transistor output stage. Its dedicated mono-channel configuration allows the amplifier to focus on accurate signal amplification while maintaining low distortion performance.

A signal-to-noise ratio greater than 97dB and THD+N below 0.01% contribute to clean signal reproduction across its operating range. The amplifier accepts low-level input signals from 0.3V to 10V, allowing compatibility with a variety of audio sources and processors.

Sound Performance

The CS1 is designed with an emphasis on analytical capability and detail reproduction. Its presentation focuses on revealing musical information clearly, allowing subtle details within recordings to be reproduced with greater definition.

The amplifier is engineered to maintain accuracy throughout the signal path, helping preserve tonal nuances and musical texture while supporting the performance potential of the connected loudspeaker.

Product Positioning

Within the Rebec amplifier lineup, the CS1 is positioned as a dedicated mono Class AB amplifier with a focus on detail retrieval and signal accuracy. Its sound character differs from the warmer presentation found in other RE Series amplifiers, placing greater emphasis on resolution and the reproduction of fine musical details.
