Full mono construction

Inside the preamplifier, circuits and components are securely mounted to a sturdy 8 mm thick aluminum frame and kept completely separate for the left and right channels. This reliably prevents unwanted mutual interference, resulting in further improved electrical characteristics and perfectly pure sonic performance.

Ultra-smooth tactile feel

Turning the volume knob on the front panel causes the actual volume level position to be detected. The corresponding combination of weighted amplifiers then in turn adjusts the volume. The volume sensor mechanism is made of a massive aluminum block extruded and finished with utmost precision. The knob provides an exquisite tactile feel when rotated and ensures extremely accurate position detection. The entire mechanism is supported by a floating suspension using insulators, which also allows extremely quiet motor-driven operation when the remote commander is used.

Ideal left/right power supply configuration

The power supply circuitry not only acts as the energy source of an amplifier, it also has a dramatic influence on its sound. The C-2900 features a newly developed type of high-efficiency toroidal transformer in a cast-aluminum case with thermal dissipation fins. Each channel has its own transformer, along with a pair of custom-made electrolytic filtering capacitors rated for high capacity and excellent sonic properties. This arrangement provides ample power reserves for effortless operation.
