Floating and Balanced Preamplifier
The C-5000 features fully balanced and discrete circuit transmission across all stages of the signal path at Tone Defeat.

The patented floating design is adopted across the phono EQ, input amp and line amp stages — removing the influence of ground noise from the signal.

Symmetrical, Folding-Book Circuit Design
The folding-book design for the preamplifier PCB mirrors the left and right signal paths for precise matching and layout.

With each channel physically identical, the C-5000 is capable of the most accurate reproduction of audio, which is both wide and deep.

Further, the ground loop is minimized when other components are connected.

Dual Toroidal Transformers
Adopting independent, dual toroidal transformers for the left and right channels delivers optimal separation and therefore produces a sound stage which is faithful to the original source.

Low magnetic leakage lowers adverse impact on the audio signal. Following detailed research based on trial listening, the power transformer was enclosed in a copper-plated case to suppress magnetic flux and vibration. This also assists in minimizing the influence of flux in the phono circuit.
This realizes an even and spacious sound due to enhanced reproduction of detailed signals.

Low-Impedance Design
By copper-plating the chassis to minimize the influence of voltage on the circuit, the C-5000 is capable of expressing the subtlest nuances as well as powerful bass.

Additionally, thick screw-type wires are utilized to reduce the impedance of the power supply and maximize the transmission of musical information.

Original Design
The C-5000 was designed from the ground up to deliver the ultimate in listening experiences — down to its aesthetic and even its touch.
The knobs and lever switches feature original designs to communicate both innovation and craftsmanship.

The volume knob is both rigid and precise — employing ball-bearings and precision-cut aluminum to achieve its touch while the lever switches have also been refined for enhanced operation.

Custom-Designed Feet
Every aspect of the C-5000 was carefully considered when designing this flagship model. Its construction exudes master craftsmanship and reflects an obsession with achieving the highest levels of performance.

The feet are no exception. Like the M-5000, the custom heavy-duty brass feet function either as fully supported spikes or with a scratch guard base for use on delicate surfaces.
