AudioQuest Carbon USB Cable - USB-A to USB-C - 1.5 Meter

What It Does in Your System

Serious Silver Content for the USB-C Devices You Already Own

This 1.5-meter cable connects a computer, server, or streamer with a standard USB-A port to a DAC or audio device with a USB-C input. Standard-A on one end, the reversible oval USB-C connector on the other.

Carbon sits high in AudioQuest's digital range and represents a real jump in silver content — 5%, against Cinnamon's 1.25% and Forest's 0.5%. That's the step where the silver stops being a light plating and starts being a significant portion of what the signal actually travels on.

Silver Exactly Where the High-Frequency Signal Lives

USB audio signals are high enough in frequency that they travel almost entirely on the outer surface of a conductor rather than through its core. AudioQuest exploits that directly: Carbon's semi-solid concentric Long-Grain Copper conductors carry 5% silver plating right at the surface, so performance approaches that of a solid silver cable at a price much closer to copper.

The semi-solid concentric construction uses fewer, larger strands that hold fixed positions along the cable's length, which sharply reduces strand-interaction distortion. The audible payoff is lower jitter — cleaner transient attack, and a top end that stays composed rather than getting hard.

Carbon-Loaded Shielding That Keeps Noise Off Your Ground

On a USB link, the real risk isn't dropped data — it's radio-frequency noise riding the shield straight into your DAC's ground reference. Carbon's negative conductors are wrapped in partially conductive carbon-loaded polyethylene, with alternating layers of metal and carbon-loaded synthetics shielding the shield above that.

A carbon layer also damps interaction between the positive and negative conductors, while Hard-Cell Foam insulation — nitrogen-injected for high air content, and stiff enough to hold signal-pair geometry constant — keeps impedance stable down the full run.

Is This Right for You?

A quick check before you add it to your cart:

• Confirm your DAC's input is USB-C, not USB-B. Many desktop and component DACs use the square USB-B connector instead. AudioQuest builds Carbon in USB-A to USB-B, USB-C to USB-C, and USB-C to USB-B as well, so there's a version for whatever you have.
• This is an audio cable, not a video cable. It won't carry a display signal from a laptop to a monitor. It's built and specified for USB audio, and it's a known point of confusion with USB-C.
• 1.5 meters covers a desk or short rack run. Enough to reach from a laptop to a DAC across a desktop, or from a shelf to a component below. Measure your actual path — a shorter length is tidier if it reaches.

Setup & Installation

Plug the USB-A end into your computer, server, or streamer and the USB-C end into your DAC. USB-C is reversible, so it seats either way up. Most DACs are recognized automatically, though some require selecting the device as your audio output and a few need a driver installed first — check your DAC's documentation.

AudioQuest builds a reinforced strain-relief system into the junction between cable and plug on all their USB cables, so the connector tolerates repeated plugging better than most. Still, pull from the connector body rather than the cable when unplugging. Keep the run clear of power supplies and AC cords where you can.

Features & Specifications

Semi-Solid Concentric 5% Silver Conductors
Silver at the conductor surface, where high-frequency digital signals actually travel, with fixed-position strands that reduce distortion and jitter.

Multi-Layer Carbon-Based Noise-Dissipation
Carbon-loaded polyethylene on the negative conductors plus alternating metal and carbon-loaded layers keep RF noise off your DAC's ground reference.

Hard-Cell Foam Insulation
Nitrogen-injected air pockets absorb negligible energy, while the material's stiffness maintains critical signal-pair geometry along the full run.

Reinforced Strain Relief
A purpose-built strain-relief system at the cable-to-plug junction adds real durability where USB cables usually fail.

Frequently Asked Questions

Will this carry video from my laptop to a monitor?
No. This is a USB audio cable and doesn't support video over USB-C. If you need a display connection, you want a cable specified for DisplayPort Alt Mode or Thunderbolt instead.

How does Carbon compare to Cinnamon and Forest?
The line steps up primarily through silver content. Forest uses 0.5% silver plating, Cinnamon 1.25%, and Carbon 5% — a substantial jump. Carbon also moves to semi-solid concentric conductors and multi-layer carbon-based noise dissipation, where the models below use a metal-layer system.

Does a USB cable really change the sound? It's just data.
The bits generally arrive intact — that's not the variable. What differs between cables is how much radio-frequency noise rides along the shield into your DAC's ground reference, and how stable the signal timing is. That's what Carbon's silver surface, carbon-based shielding, and Hard-Cell Foam geometry address, which is why the effect shows up as lower jitter and quieter backgrounds rather than missing data.
