【M&M DESIGN 7N-MA9000 (2.0m) High-End Line Cable】
This line cable is chosen by people who want to convey the sound with as much naturalness as possible—down to the amount of sonic information and the smallest nuances.
The internal conductors use ultra-high-purity conductors made by Mitsubishi Materials (99.99998% purity). Combined with years of expertise in cable design, it is finished with a focus on signal transmission for car audio.
Even with the same product, a cable is a component whose impression can change depending on the system configuration, connection method, and routing. It’s important to select it while considering the overall balance of the vehicle, confirming how it pairs with your amplifier and DSP.
If you want to “refine the current sound a little more carefully” or “bring out the full performance of your equipment,” let’s think it through together while reviewing the system details.
