Mogami W2497 Cable Specifications
The W2497 utilizes a patented Double-Cylindrical structure designed to deliver rich detail and minimal signal loss.
Capacitance: 67 pF/m (at 1kHz) — Excellent for low-loss signals.
Impedance: 75 Ohm characteristic impedance — Suitable for both analog audio and digital SPDIF connections.
Outer Diameter: 8.0mm (0.315") — A thicker, beefy cable that requires specific high-quality RCA connectors.
Conductor: Neglex III PCOCC (Pure Copper by Ohno Continuous Casting) for maximum audio fidelity.
Resistance: DC Resistance is 55 mOhm/m
 
This is a thicker type of cable that works well with heavier devices but if you want a shorter cable for smaller devices, the wire does not flex very far and it may dictate how your light weight devices sit.
 
Prices start at $130 for a stereo left and right pair at 0.5 meters in length.
