B.M.C.'s CS3 is a Load-Effect Free (LEF) Amplifier with an option to upgrade it to a LEF Stereo Power Amplifier.

The CS2 is a power amplifier without a preamplifier for a short, pure signal path. It features a Volume Control using our exclusive Discrete Intelligent Gain Management (DIGM) system, and an input selector. The lossless DIGM volume adjustment eliminates unnecessary signal attenuation at the input, as well as unnecessary high amplification.

Combining the CS3 with a B.M.C. Digital-to-Analog Converter (DAC) transforms it into a LEF stereo power amplifier that offers DIGM gain adjustment set by the DAC's volume control. In addition, B.M.C.'s balanced Current Injection (CI) input enhances the immediacy of reproduced music by processing the signal current of the source until it reaches the speaker's output voltage. B.M.C.'s LEF output stage avoids distortion before it occurs by relieving the sound-critical LEF single-ended Class-A transistor of all duties other than providing perfect signal reproduction.
